Answer:

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!
