3x^3(4x^4+5x^2-2x-9+2x^2)

(not multiple choice btw)

12x^7+21x^5-33x^3

Step-by-step explanation:

12x^7+15x^5-6x^3-27x^3+6x^5

12x^7+21x^5-33x^3

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
