1. equation A is multiplied by -2, yah, right form

2. wrong, yo didn't distribute the -2 at all, it just dissaperaed, who taught that student how to do math?

Answer:
x = 4
Step-by-step explanation:
BE bisects AD and AC, hence is a mid- line segment. Hence BE is half of CD
CD = 12 ⇒ BE = 6, that is
x + 2 = 6 ( subtract 2 from both sides )
x = 4 → C
If you add them all together (7+4+7=18) the answer would be C.
V= 3
because
15=5*v
3*5=15
so v=3
