Can some one help me

see below

Step-by-step explanation:

10. CD = AC / 2 = 6 and CE = BC / 2 = 4.

11. DG = DH * 2.5 = 10

   HG = DG - DH = 10 - 4 = 6

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
