Answer: see explanation

Step-by-step explanation:

you would add AB (14) and BC (3x-4) to get the length of AC (4x+4).

14 + 3x-4 = 4x + 4

then, just solve for the value of x. (isolate x)

and then plug the value of x back in to "4x+4" and that's your answer.

Answer:

6

Step-by-step explanation:

14+3x-4=4x+4

3x+10=4x+4

3x-4x=4-10

-1x=-6

x=6
