well, if AC is the full length, then AB and BC must both be half length each (therefore, they are equal)
so we can write this as:
AB = BC
3x+4 = 12x-13
3x = 12x - 17
-9x = -17
x = 17/9
i dont have a calculator on me so i'll let you punch that in and there's your answer. :)
thanks i've been stuck on this question for awhile, so i was just working on other assignments
