Question

HELP ME PLEASE I NEED HELP

Answer 1

a= 2-2(-4)= 10

b= -4^3+2^3+3(-4)(2) (-4 - 2)= 8

Answer 2

10, and -8.

Explanation:

So we know a = -4

We also know that b = 2

Lets plug in a = -4 and b = 2 into b-2a:

2-2(-4)

=

2--8

A minus and minus make a plus, so:

2+8 = 10

So the answer is 10.

Next lets plug in a = -4 and b = 2 into
`(a+b)^3`:

`(-4+2)^3`

=

`(-2)^3`

=

-8

So the second answer is -8.

Hope this helps!
