Question

I’m stuck on this question if someone could help me I would highly appreciate:)

Answer 1

AB = 8

Explanation:

Given B is the midpoint of AC , then

AB = AC , that is

7x - 6 = 12 - 2x ( add 2x to both sides )

9x - 6 = 12 ( add 6 to both sides )

9x = 18 ( divide both sides by 9 )

x = 2

Then

AB = 7x - 6 = 7(2) - 6 = 14 - 6 = 8

Answer 2

8 is the answer...

Hope it helps
