Question

I need help with this question

Answer 1

Explanation:

given: B is the midpoint of AC

so, AB=BC

i,e, x + 8 = 4x - 4

8 + 4 = 4x - x

12 = 3x

12/3 = x

∴ x = 4

so, AB = x + 8 = 4 + 8 = 12

BC = 4x - x =4(4) - 4 = 16 - 4 = 12

12 + 12

о------------о------------о

A B C

AC = AB + BC = 12 + 12 = 24

AC = 24

Answer 2

Answer:24

Step-by-step explanation: AB= x+8, BC=4x-4. They are equal to each other because B is the midpoint of A and C. therefore, we set them to equal, and simplify to 3x=12.(x+8=4x-4,-x, 8=3x-4, +4, 3x=12 ) That means x = 4, and then we plug that into the equations, getting AB and BC are both 12. We add them together and get 24/
