2 answers:
Answer:
AC = 12x + 20
Step-by-step explanation:
Combine the terms:
AB + BC = AC
AB = 8x + 2
BC = 4x + 18
Plug in the corresponding terms to the corresponding variables:
(8x + 2) + (4x + 18) = AC
AC = 8x + 4x + 18 + 2
AC = 12x + 20
12x + 20 is your answer for AC.

Answer:
68
Step-by-step explanation:
8x+2=4x+18
8x-4x=18-2
4x=16
x=4
Now we substitute it back in:
8(4)+2+4(4)+18-
32+2+16+18=
