Answer:
Part A: 6x + 20
Part B: Expression G and H are not equivalent for any value of x.
Step-by-step explanation:
Part A:
G = 2(3x + 10)
G = 6x + 20
Part B:
6x + 20 = 6x + 12
-20 -20
6x = 6x - 8
-6x -6x
0 = -8
No solution. This means that expressions G and H are not equivalent for any value of x.
