Question

The expression 12x+15x-11x can be combined because of which property

A. commutative property of addition
B. distributive property
C. additive inverse property
D. multiplicative property

Answer 1

The answer would be A. Commutative property of addition 

Answer 2

Option A.

Explanation:

Commutative property of addition says that if we add two or many numbers, order doesn't matter.

Let there are three numbers a, b, and c.

When we add them by commutative property, result will remain same.

If we add [(a + b)+ c] or [a + (b + c)], result will be same.

Therefore, 12x + 15x - 11x = (12 + 15 - 11)x

= (27 - 11)x

= 16x

Option A. Commutative property will be the answer.
