Question

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

Answer 1

property of like terms because they are alike if u solve it all it will be like 27x-11x =16x

Answer 2

The expression
`12x+15x-11x` can be combined because of the commutative property of addition.

Explanation:

A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that

`12x+15x-11x`

all are examples of monomials.

The commutative property of addition says that changing the order of addends does not change the sum.

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

Therefore,

`12x + 15x - 11x = (12 + 15 - 11)x\\12x + 15x - 11x = (27 - 11)x\\12x + 15x - 11x = 16x`
