Answer:

-41

Step-by-step explanation:

Here your a(x) = |13 - 2x|, and your b(x) = 8x - 14.

b(-2) is found by substituting -2 for x:  b(-2) = 8(-2) - 14 =  -16 - 14 = -30

-a(12) is found by substituting 12 for x in a(x):  a(12) = |13 - 2(12)| = |13 - 24| = 11

Then b(-2) - a(12) = -30 - 11 = -41
