PLEASE HELP, QUICKLY!!!

| -4b -8 | + | -1 - b^2 | + 2b^3 ; b= -2

I have tried many different attempts but I can't solve it!!! I'm In Algebra 2 and this is part of my Unit Test of "Expressions, Equations, and Inequalities"

Answer 1

Substitute the given value of b into the expression and simplify to find the value.

Step-by-step explanation:

To solve this expression, substitute the given value of b into the expression. The given value is b = -2.

| -4b -8 | + | -1 - b^2 | + 2b^3 ; b= -2

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

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

= | 0 | + | -5 | -16

= 0 + 5 - 16

= -11

Answer 2

-11 is the answer

Step-by-step explanation:

Use the demos calculator. My work is attached below, it is the one on the bottom. I literally just did this with my math teacher. These are all correct. I am assuming you go to connections like me so I gurantee these are correct.
