Evaluate the expression |4b-4| +3b for b= -2 a. 6 b. -18 c. 10 d. 18

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. So:

|-12| becomes 12

12 - 6 = 6

A. 6 is your answer

hope this helps
