3x3

Answer 1

 the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.

Answer 2

option 2 and 6

Explanation:

Given : Monomial
`3x^2y`

To find : Adding which terms to
`3x^2y` would result in a monomial? Check all that apply.

Solution :

Monomial is when the number of terms is only 1.

1)
`3xy`

Adding in given monomial

`3x^2y+3xy` is a binomial

2)
`-12x^2y`

Adding in given monomial

`3x^2y+(-12x^2y)=-9x^2y` is a monomial

3)
`2x^2y^2`

Adding in given monomial

`3x^2y+2x^2y^2` is a binomial

4)
`7xy^2`

Adding in given monomial

`3x^2y+7xy^2` is a binomial

5)
`-10x^2`

Adding in given monomial

`3x^2y-10x^2` is a binomial

6)
`4x^2y`

Adding in given monomial

`3x^2y+4x^2y=7x^2y` is a monomial

7)
`3x^3`

Adding in given monomial

`3x^2y+3x^3` is a binomial

Therefore, Option 2 and 6 are the terms giving a monomial.
