PLEASE HELP

Answer 1

The question is wether for the first positive value we consider (-4)×(-2) or -4×(-2)

Answer 2

-11

Explanation:

`|-4b-8|+|-1-b^2|+2b^3`

Given the value of b=-2

Plug in the value of -2 for b and evaluate

`|-4b-8|+|-1-b^2|+2b^3`

`|-4(-2)-8|+|-1-(-2)^2|+2(-2)^3`

`|8-8|+|-1-4|+2(-8)`

`|0|+|-5|-16`

`0+5-16=-11`

Final answer is -11
