The length of a rectangle is the sum of the width and 4. The area of the rectangle is 32
units. What is the width, in units, of the rectangle?
Answer:
The width of rectangle w = 4 units
Step-by-step explanation:
We are given:
Width of rectangle = w
Length of rectangle = w+ 4
Area of rectangle = 32 units
We need to find width of the rectangle
The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]
Putting values and finding width of rectangle
[tex]Area\:of\:rectangle=Length\times Width\\32=(w+4)\times w\\32=w^2+4w\\w^2+4w-32=0[/tex]
We need to solve this quadratic equation to find width (w)
We will use factorisation and break the middle term.
[tex]w^2+4w-32=0\\w^2+8w-4w-32=0\\w(w+8)-4(w+8)=0\\(w-4)(w+8)=0\\w-4=0\:or\:w+8=0\\w=4\:or\:w=-8[/tex]
Since width of rectangle can't be negative, so rejecting w=-8
Therefore, the width of rectangle w = 4 units
Solve the inequality.
10. -3p > -48 (1 point)
O p<16
O p>-51
O p<-16
O p> 16
What one
Answer:
p < 16
Step-by-step explanation:
-3p > -48
Divide both sides by -3. Remember to change the direction of the inequality sign when you multiply or divide by a negative number.
-3p/(-3) < -48/(-3)
p < 16
Answer: p < 16

Answer:
x = 34°Step-by-step explanation:
Use property of exterior angles:
Exterior angle = sum of non-adjacent interior anglesHere we have:
∠D + ∠E = ∠EFG∠EFG = ∠EFH + ∠HFG = 90° + 42° = 132°So the equation is:
2x + 64° = 132°2x = 132° - 64°2x = 68°x = 68°/2x = 34°If you think it is not 34°, then your question must be asking to find something else (e.g. angle D, which is 68°)

Reggie started a running program to prepare for track season. Every day for 60 days, he ran a half hour in the morning and a half hour in the evening. He averaged 6.5 miles per hour. At this rate, what is the total number of miles Reggie ran over the 60-day period?
Answer: 390 miles
Step-by-step explanation:
Reggie ran for half an hour in the morning and half an hour in the evening.
That is a total of 1 hour for the day.
He runs 6.5 miles in one hour.
In 60 days he would have ran;
= 60 * 6.5
= 390 miles

Solve the Equation
–x + 8 + 3x = x – 6
A. x = –18
B. x = –14
C. x = 2
D. x = 4
Answer:
x= -14
Step-by-step explanation:
-x+3x-x=-8-6
x= -14
-x+8+3x=x-6
the first thing we need to do is move the x's to the left and the numbers to the right
when moving a number from one side to another it's sign is changed
-x+3x-x=-6-8
x=-14

The value of a car is $15,000 and the depreciates at a rate of 10% per year. What's the car value by the 8th year
Answer: $3,000.
Step-by-step explanation: The 10% of $15,000 is %1,500, so the value of the car drops by $1,500 each year. So, in eight years (8 years x $1,500), the value will drop by $12,000. Therefore, the price of the car in eight years will be the original amount minus the depreciating amount ($15,000 - $12,000), this will be $3,000.

PLEASE! 10 POINTS! For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?
Answer:
3Ax-6x = 15
3x(A-2)=15
If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2
What is CD??
A.7
B.10
C.13
D.21
Answer:
13
Step-by-step explanation:
Is there more info to this problem? I'm assuming both triangles are congruent. If so then you can assume that BC = CD
If that's the case then set them equal to each other to solve for x then plug x back into the side for CD to get the value
6x-5 = 4x+1
2x = 6
x = 3
Plug into CD 4(3) +1
= 13

Use elimination to solve the system.
2x + 3y = 1
5x – 4y = 14
help would be appreciated :)
Answer:
x = 2, y = -1
Step-by-step explanation:
To solve this with elimination, we first multiply the first equation by -2.5
Our new equations are:
-5x - 7.5y = -2.5
5x – 4y = 14
After adding these two equations together, the x cancels out and we have:
-11.5y = 11.5
Divide both sides by -11.5
y = -1
Plugging this value into y in one of the equations we have:
2x + 3y = 1
2x + 3(-1) = 1
2x - 3 = 1
Add 3 to both sides
2x = 4
Divide both sides by 2
x = 2

Answer:
Y - Adds by -5X - Adds by 2Step-by-step explanation:
It adds by negative 5 because if you add up all of the math and equations, it will all fit together.
Here's an example.
The first one is 3 and -2, so lets add -2 by 5.
-2 + 5 = 3 --- 1st row
We can figure this out by subtracting 2 by 5, which equals 3.
( This does not apply to all equations. )
Let's add all of them by 5 now.
-7 + 5 = -2 --- 2nd row
-12 + 5 = -7 --- 3rd row
On the last row, we add -12 by -5 and you get -17.
-17 + 5 = -12 --- 4th row
That's how you figure it out.
Hope this helps! <3

Divide both sides by 2;
x = 12
b. [tex]\frac{3x}{2}=6[/tex]
Multiply both sides by 2;
[tex]\frac{3x}{2}*2=6*2\\\\3x=12[/tex]
Divide both sides by 3;
x = 4

f(x) and g(x) are not closed under subtraction because when subtracted, the result will be a polynomial, the correct option is B.
What is Closure Property?According to Closure Property, when something is closed, the output will be same as the input.
The polynomials f(x) and g(x) can be seen in the image.
On subtracting the two polynomials, the output will be a polynomial and so it is closed under subtraction.

2. Find the distance between the points K(-2, 3) and L(4,7)
Answer:
7.21 (7.211103 exact)
Step-by-step explanation:
In this question, we have to find the distance of the two points.
To do so, we would use this equation: d = √(x2-x1)² + (y2-y1)²
Plug in your coordinates and solve:
d = √(4+2)² + (7-3)²
d = √(6)² + (4)²
d = √36 + 16
d = √52
Now, get the square root of 52:
d = 7.211103
The distance of each coordinate would be around 7.21
