Question

Which of the following shows 7 + (x + 4y) rewritten using the Associative Property of Addition?

A 7 + x + 4y

B 7x + (4 + y)

C (7 + x) + 4y

D x + (7 + 4y)

Answer 1

C. (7 + x) + 4y

Explanation:

The associative property of addition:

(a + b) + c = a + (b + c)

Therefore:

7 + (x + 4y) → (7 + x) + 4y

Answer 2

The answer is C because when you use associative, all your doing is keeping the equation just the way it is, but moving the parenthesis in difference places.

Answer:C
