Step-by-step explanation:
Commutative property swaps 2 numbers, but wont make any difference to the answer.
9+4 and 4+9 are the same amount
Answer:
B. Associative property of addition.
Step-by-step explanation:
The identity property involves zeros, so we know it's not that one.
The distributive property is when you have a number, and then two other numbers in parenthesis and you multiply the numbers by the number outside the parenthesis. (ex: 4(1 + 3) you would do 4 x 1 and 4x 3 and add them together) and we know it's not that one because it doesn't show the distribution.
The associative property states that you can re-group numbers and you will get the same answer, and since it has parenthesis, we know it's this one.
The commutative property states that you can move numbers around and still arrive at the same answer.
