Hello!
You put -2 in for b
/4(-2) - 4/ + 3(-2)
Multiply
/-8 - 4/ -6
Subtract
/-12/ - 6
Take the absolute value of -12
12 - 6 = 6
The answer is 6
Hope this helps!
Ok, so,
b = -2
plug in -2 for b
|4(-2) - 4| + 3(-2)
4(-2) = -8
|-8 - 4| = |-12|
3(-2) = -6
|-12| - 6
|x| is a absolute value of x, so that no matter what, it will be positive!
|-12| becomes 12
12 - 6 = 6
A. 6 is your answer
I really hope this helps!
