Answer:
[tex]2x^2 + 5x + 3[/tex]
Step-by-step explanation:
First, expand the original equation:
(x + 1)(2x + 3)
[tex]2x^2 + 3x + 2x + 3[/tex]
Now simplify:
[tex]2x^2 + 5x + 3[/tex]
And that's your answer!
2. Find the value of x.
Answer:
x = 3
Step-by-step explanation:
You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..
5x - 7 = 2x = 2
Therefore you can then simplify for the value x where you should get teh value 3.

Step-by-step explanation:
Step 1: Define Inequality
-3m + 18 < 3
Step 2: Solve for m
Subtract 18 on both sides: -3m < -15Divide -3 on both sides: m > 5Here we see that any number m greater than 5 would work as a solution to the inequality.
Coachella Valley of California the elevation is 215 feet below sea level.
Clara wrote this elevation as -215 feet.
Is Clara's response reasonable? Explain the given elevation with respect to its relationship to 0.
Answer:
Yes. Her answer is reasonable.
Step-by-step explanation:
Since sea level is at an elevation of 0 feet, we can express Coachella Valley as being -215 feet because it is 215 feet bellow sea level. If it were to be able sea level then it would be positive.
a council reviews the amount of bedrooms in 40 houses located in the same area. this table shows the information gathered
a) find the modal average of bedrooms
b) work out the mean average of bedrooms
number of bedrooms: frequency:
1 ---------------------------------5
2------------------------------- 10
3 -------------------------------15
4 --------------------------------7
5 --------------------------------3
Answer:
A. 3
B. 2.825
Step-by-step explanation:
Data obtained from the question include:
Number of bedrooms (x) > Frequency(f)
1 >>>>>>>>>>>>>>>>>>>>> 5
2 >>>>>>>>>>>>>>>>>>>> 10
3 >>>>>>>>>>>>>>>>>>>> 15
4 >>>>>>>>>>>>>>>>>>>> 7
5 >>>>>>>>>>>>>>>>>>>> 3
Mode =?
Mean average of bedrooms =.?
A. Determination of the modal average of bedroom.
The mode of a given set of data is the the value with the highest frequency.
Considering the table given in the question above, we can see clearly that 3 has the highest frequency. Hence 3 is the modal average of the bedroom is 3
B. Determination of the mean average of bedroom.
Mean = Σfx / Σf
Σfx = (1×5) + (2×10) + (3×15) + (4×7) + (5×3)
Σfx = 5 + 20 + 45 + 28 + 15
Σfx = 113
Σf = 5 + 10 + 15 + 7 + 3
Σf = 40
Mean = Σfx / Σf
Mean = 113 / 40
Mean = 2.825
Therefore, the mean average of bedroom is 2.825

Eddie went to Luke Base Air Force Show and brought $55 with him to spend. If admission cost him $5 and sodas were $6.25 each, what is the GREATEST number of sodas, x, Eddie can buy? USE x AS VARIABLE; NO SPACES.
Answer:
8
Step-by-step explanation:
Given that:
Eddie has gone to Luke Base Air Force Show.
Total money available with Eddie = $55
Admission cost = $5
Cost of each soda = $6.25
To find:
The greatest number of sodas that can be bought by Eddie ?
Solution:
Let the greatest number of sodas that can be bought by Eddie = [tex]x[/tex]
Now, the total money spent by Eddie will be equal to the admission fee and the cost for buying the [tex]x[/tex] number of sodas.
Cost for [tex]x[/tex] number of sodas = Cost of one soda multiplied by [tex]x[/tex] = $6.25 [tex]\times x[/tex]
Writing equation as per given statement:
Total money = $55
[tex]55 = 5 +6.25x\\\Rightarrow 6.25x = 55-5\\\Rightarrow 6.25x = 50\\\Rightarrow x = \dfrac{50}{6.25}\\\Rightarrow \bold{x = 8}[/tex]
Therefore, a maximum of 8 number of sodas can be bought.
1) Which pair of triangles is congruent by Side - Side - Side? *
Please do all of them and don't answer if you don't know thanks in advance :)
best answer will get brainliest and multiple thanks on some of your other answers and this one
Answer:
The fourth pair of triangles.
Step-by-step explanation:
Looking at the diagram for the fourth pair of triangles, we see that two pairs of sides have been marked as having the same length, and the remaining side is shared by the two triangles, hence guaranteeing that side's congruence. Therefore, the fourth pair of triangles is congruent by SSS.
The first pair of triangles are congruent by ASA, due to the middle pair of angles being congruent (vert. opp. ∠s), hence providing the condition for SAS.
The second pair of triangles should be SAS, also known as Side - Angle - Side, due to two angles and one side being marked as congruent, and those two angles surrounding the side marked as congruent.
The third pair of triangles should be SAS, due to them sharing a common side and a pair of sides marked congruent, surrounding the right angle. The reason why it is not RHS is because the pair of hypotenuses are not congruent, hence not fulfilling the condition of Right Angle - Hypotenuse (here!) - Side.
Hope this helped!

Which percent is equivalent to 0.3?
A. 0.003%
B. 0.03%
C. 3%
D. 30%
Answer:
D, 30%
Step-by-step explanation:
you move the decimal point twice to the right
Answer:
D. 30%
Step-by-step explanation:
This is the answer because:
1) When you convert decimals to percents, you have to remember the two main decimal places:
0.00 = The hundredths place
0.00 = The tenths place
2) Whenever there is a decimal that is in the hundredths place, it will equal a one digit percent. For example, 0.07 = 7%.
3) Whenever there is a decimal that is in the tentsh place, it will equal a two digit number. For example, 0.3 = 30%.
4) Another way to solve it is to convert the decimal to a percentage by multiplying the decimal by 100 .
Therefore, the answer is 30%.

The dance committee of Pine Bluff Middle School earns \$72$72dollar sign, 72 from a bake sale and will earn $4 dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $400. Write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
Answer:
t > 82
Step-by-step explanation:
Given that,
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
We need to find an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
The committee earns $4 for each ticket. It means they will earn $4t.
$72 is constant as they earn it from bake sale.
The total earning must be greayer than $400.
ATQ,
4t + 72 > 400
We can solve the above inequality to find the value of t.
4t > 328
t > 82
Hence, the committee could sell more than 82 tickets to have money left over after they pay for this year's dance.

Answer:
Equation: [tex]2(x+8)+2(3x-5)+23 = 126[/tex]
[tex]x = 12.125[/tex]m
[tex]AB = 20.125[/tex]m
[tex]EF=31.375[/tex]m
Step-by-step explanation:
The equation of the perimeter of this shape can be written as:[tex]2(x+8)+2(3x-5)+23 = 126[/tex] (Sides with the same number of dashes are equal in length)
Which becomes:
[tex]2x+16+6x-10+23=126[/tex]
[tex]8x+29=126[/tex]
[tex]8x=97[/tex]
[tex]x= 12.125[/tex]
Since AB = [tex]x+8[/tex], we can substitute to get the length of AB:
[tex]x+8 = 12.125+8[/tex]
[tex]=20.125[/tex]
We can also use substitution to solve for the length of EF:
[tex]3x-5=3(12.125)-5[/tex]
[tex]=31.375[/tex]

Predict the next number in the sequence: 1, 4, 16, 64…
512
244
384
256
Step-by-step explanation:
Notice that:
1 * 4 = 4,
4 * 4 = 16,
16 * 4 = 64.
Each term is 4 times of the previous term.
Hence the next term would be 64 * 4 = 256.
the value of a second-hand car is £8000. Each year it loses 20% of its value at the start of this year. work out its value in 5 years time
pls answer,I will also mark the brainest and I will rate 5 out of 5 stars pls show working out
Answer:
the value in the five years is £2,621.44
Step-by-step explanation:
The computation of the value in the five years is given below:
= The value of the second car × (1 - losses percentage)^number of years
= £8,000 × (1 - 0.20)^5
= £8,000 × 0.80^5
= £8,000 × 0.32768
= £2,621.44
Hence, the value in the five years is £2,621.44
We simply applied the above formula so that the correct value could come

Step-by-step explanation:
4w^2-m+15w^2
19w^2-m
The second bracket becomes 15w^2 because it's a negative number multiplied by -1
(4w^2-m)+15w^2

The angles below are supplementary, What is the value of x?
Answer:
x = 12
Step-by-step explanation:
Supplementary angles add up to 180 degrees therefore (6x + 48) and 60 should add up to 180. Like this:
6x + 48 + 60 = 180
Now solve:
6x + 48 + 60 = 180
6x + 108 = 180
6x = 72
x = 12
Therefore, the answer is x = 12.
I hope this helps!!
- Kay :)
Answer: x=12
Step-by-step explanation:
6x + 48 + 60 = 180
6x + 108 = 180
6x = 72
x=12
