Question

Name the property demonstrated by the following equation: (5 + 4) + 6 = 5 + (4 + 6).

Answer 1

The answer for that is D

Answer 2

The associative property states that you can add or multiply and get the same answer, despite how the numbers are grouped (or where you place the parenthesis).

So, I would go with A. Associative Property of Addition. B makes no sense since there is no multiplication used here. 

I hope this is helpful! :D
