answer

CD = 38

solving steps

4x – 5 = 2x + 7

4x – 5 – 2x = 7

2x = 7 + 5

2x = 12

2x/2 = 12/2

x = 6

4(6) – 5 + 2(6) + 7

24 – 5 + 12 + 7

M = 38

Answer:

C

Step-by-step explanation:

Given that M is the midpoint of CG , then

CM = MG , that is

4x - 5 = 2x + 7 ( subtract 2x from both sides )

2x - 5 = 7 ( add 5 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Then

CG = CM + MG = 4x - 5 + 2x + 7 = 6x + 2 = 6(6) + 2 = 36 + 2 = 38
