Answer:
D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Step-by-step explanation:
Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.
or, for any numbers A, B and C
A + ( B +C) = (A +B) + C
Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.

Answer:4 to the power 15
Step-by-step explanation:
If one power is over the another power you need to multiply both of them..
So here the base is 4 and above it 3 and 5 will be multiplied3×5=15..so the answer is the 3rd one..
Here are 2 properties you must check..
