Question

Evaluate the expression for the given value of the variable: PLEASE HELP

Answer 1

Answer:

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

Answer 2

Answer:

-11

Step-by-step 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
