Answer: x³+2x²-15x

Step-by-step explanation:

1. Expand

(x²-3x)(x+5)

2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd

x³+5x²−3x²−15x

3. Collect like terms

x³+(5x²−3x²)−15x

4. Simplify

x³+2x²-15x

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

SpyIntel [72]

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

$3x+8y=55$ -----> equation A

$x+y=15$

$x=15-y$ -----> equation B

Substitute equation B in equation A

$3[15-y]+8y=55$

$45-3y+8y=55$

$5y=55-45$

$5y=10$

$y=2$

Find the value of x

$x=15-y$

$x=15-2=13$

therefore

the answer is

the number of multiple choice question are $13$

the number of free response question are $2$

6/8 equals how many quarters?

allsm [11]

Your answer would be 3/4 (three quarters).

-----------------------------------------------------------------------------------------------------------------

This can be simplified even further because both the numerator (6) and the denominator (8) can be divided by 2.

So-- 6 divided by 2 would be 3, and 8 divided by 2 would be 4. 3/4 cannot be simplified even further so this would be your final answer.

I hope this helped you out a bit :]
