Simplify
-3x^3 (-2x^2+4x-3)
a -5x^5 +x^4 -6x^3
b -6x^6-12x^4 +9x^3
c 6x^5-12x^4+9x^3
d 6x^6-12x^3+9

Answer is 6x^5 - 12x^4 + 9x³

Step-by-step explanation:

⇒ 6x^5 - 12x^4 + 9x³

22 dimes and 9 nickels

step-by-step explanation:

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!
