Answer:
use distance formula for the sides of the triangle
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6
6 ( 31/6 - 4) = 7
186/6 - 24 = 7
186/6 = 144/6 = 7
42/6 = 7
7 = 7
You need to write down the full question
1/2 because 2*2*2 equals 8 so all you do is put it in fraction form. 1/2*1/2*1/2= 1/8
