Step-by-step explanation:
We assume you want factors that use real integers.
a) 121x² +36y² . . . . cannot be factored using real numbers
b) (4x +4)(x +1) = 4(x +1)²
c) x(x² -4) = x(x -2)(x +2)
d) x⁴ -15n³ +12n² . . . . cannot be factored*
_____
* If the polynomial is n⁴ -15n³ +12n², then it factors as n²(n² -15n +12).

A. 10x + 6
B. 12x + 4
C. 2(5x + 3)
D. 2(6x + 2)
Which two expressions are equivalent to 2(5x + 2 + x)? (1 point)
A and C
B and D
A and D
B and C
Answer:
B and D
Step-by-step explanation:
Simplify the given expression as shown below:
2(5x+2+x)= 2(6x+2) = D
Also
2(6x+2) = (2×6x) + (2×2)= 12x + 4 = B
Hence Both B and D are equivalent to 2(5x+2+x)

Van purchased a DVD player on sale. The original selling price was $175.80. The sale price was $150.65. Find the percent markdown.
Answer:
14%
Step-by-step explanation:
In this question, we have to find the percent markdown of the cost of the DVD player.
We know that the original price was $175.80, and now it is $150.65
To find the markdown, lets set this up as a proportion:
[tex]\frac{\$down}{original\$}=\frac{\%down}{100\%}[/tex]
First, lets find how much money was downed due to the sale. Do this by subtracting the sale cost from the original.
175.80 - 150.65 = $25.15
Since we now know our markdown cost, we can plug in the information to our proportion:
[tex]\frac{25.15}{175.80}=\frac{x}{100}[/tex]
Since we're solving for the percent markdown, we will replace the %down with an x, since we will be solving for x.
Solve for x:
[tex]\frac{25.15}{175.80}=\frac{x}{100}[/tex]
Cross multiply.
[tex]175.80x=2,515[/tex]
Divide both sides by 175.80
[tex]x=14.30602[/tex]
When you round the decimal to the nearest whole, you would get a markup of 14%

what is the third angle of a triangle if the other two are (3x-20)° and (4x+10)°
Answer:
The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.
A + (3x-20) + (4x+10) = 180
A = 180 - (3x - 20) - (4x + 10) = 190 - 7x
Emilia conducted an experiment with Growing crystals. At the beginning of the experiment, she had a crystal that measured 6MM. She recorded the length every hour and notice that it increased by 12MM every hour. Emilia Task to the relationship between time and length of the crystal. Which towo ordered pairs are on Emilia's graph? (1,12) (2,30) (4,36) (5,66) (7,54)
Answer: (2,30), (5,66)
Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.
12x2= 24
24+ 6= 30,
12x5= 60
60+6= 66

a pile of coins, consisting of quarters and half dollars is worth $11.75. If there are 2 more quarters than half dollars, how many of each are there?
Answer:
Hope it helps ..and ☆HAPPY New year MY DEAR ☆
Step-by-step explanation:
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dolla
17 quarters, 15 half dollars

Students majoring in psychology surveyed 200 of their fellow students about their dreams. The results of the survey are shown in the Venn diagram. Let B be the event that the participant dreams in black and white and let C be the event that the participant dreams in color.
What is the probability that a randomly selected participant dreams in black and white or color?
Answer:
0.13
Step-by-step explanation:
4/200=0.02 12/200=0.06 10/200=0.05
0/02+0.06+0.05=0.13
The probability that a randomly selected participant dreams in black and white or color is 0.13.
What is probability ?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. "
Probability of all black = 4/200=0.02
Probability of all white = 12/200=0.06
Probability of all other color = 10/200=0.05
So, probability that a randomly selected participant dreams in black and white or color =0.02+0.06+0.05=0.13
Hence, the probability that a randomly selected participant dreams in black and white or color = 0.13

A polynomial multiples by a polynomial is a polynomial
A polynomial multiple by a polynomial is always a polynomial. The given statement is true.
What are polynomials?Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.
When two polynomials are multiplied by each other, then each term of the first polynomial is multiplied by each term of the second polynomial.
The result is always a polynomial, regardless of what the coefficients might be of any of the terms, including the leading coefficients.
Thus, A polynomial multiples by a polynomial is always a polynomial.

A rocket is shot straight into the air at an initial velocity of 70 feet/second.
The height of the rocket after t seconds is represented by the formula
h = 70t - 5tº. What is the maximum height the rocket reaches?
235 feet
265 feet
215 feet
245 feet
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[tex]h=70t-5t^2[/tex]
[tex]\dfrac{dh}{dt}=70-10t[/tex] [Differentiate both sides w.r.t. t]
Put
[tex]\dfrac{dh}{dt}=0\\\\\Rightarrow\ 70-10t=0\\\\\Rightarrow\ t=\dfrac{70}{10}=7[/tex]
Also, [tex]\dfrac{d^2h}{dt^2}=-10<0[/tex] i.e. height is maximum at t=7.
Maximum height = [tex]h=70(7)-5(7)^2 = 490 - 245= 245\text{ feet}[/tex]
Hence, the maximum height the rocket reaches = 245 feet.
