Question

9.

Which of the following demonstrates the Associative Property?
A. 2(3 - a) = 2.3+2.a
B. 4(a + b) = 4ab
C. -2(a-3) = -2a +6
D. (a + c)+ a = a +(c + a)

Answer 1

the answer is D!

Explanation:

the associative property states "rearranging the parenthesis in an expression will not change the result."

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

they're still going to equal the same! :)
