Answer:
Step-by-step explanation:
GK = GH + HJ + JK
But GJ = 3x + 5, HJ = x, HK = 4x - 1
Find GH:
GH = GJ - HJ
GH = (3x + 5) - x
GH = 3x + 5 - x
GH = 2x + 5
Find JK:
JK = HK - HJ
JK = (4x - 1) - x
JK = 4x - 1 - x
JK = 3x - 1
Find GK:
GK = GH + HJ + JK
GK = 2x + 5 + x + 3x - 1
GK = 6x + 4
Therefore, GK = 6x + 4
