Question

HELP ME PLEASE I NEED HELP

Answer 1

Answer:

10, and -8.

Step-by-step 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!

Answer 2

Answer:

a= 2-2(-4)= 10

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