The commutative property does not work for which operations? check all that apply. a. b. - c. + d. x

Commutative property works for addition and multiplication

Step-by-step explanation:

A. ÷

We need to check if

Take a = 4 and b = 2

So,

Therefore, commutative property does not work for division.

B. -

Take a = 7 and b = 10

So,

Therefore, commutative property does not work for subtraction

C. +

Take a = 8 and b = 9

So,

Therefore, commutative property works for addition.

D. ×

Take

So,

Therefore,  commutative property works for multiplication.

So, commutative property works for addition and multiplication.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
