Respuesta :
This is the Commutative Property of Addition. The order is switched but the numbers aren't. This also works in multiplication, but NOT in subtraction and division.
this is addition so you can cross out answers A and D
communtative=a+b=b+a
associative is
a+(b+c)=(a+b)+c
so the answer is commutative property of addition or B
communtative=a+b=b+a
associative is
a+(b+c)=(a+b)+c
so the answer is commutative property of addition or B
