Let's begin by listing out the given information:
The commutative property states that for addition, the order in which we add numbers does not change their sum & for multiplication, the order in which we multiply does not change their product.
Mathematically expressed as:

Therefore, the commutative property of this is:

Therefore, Option D is the correct answer
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.
The 1st expression is the only one that reproduces the terms being added.
