Answer:
By adding 12x²y and 4x²y result will be a monomial.
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Adding which terms to 3x²y would result in a monomial? Check all that apply.
3xy
–12x2y
2x2y2
7xy2
–10x2
4x2y
3x3
1). 3x²y + 3xy → [Binomial]
2). 3x²y - 12x²y = -9x²y → [Monomial]
3). 3x²y + 2x²y² → [Binomial]
4). 3x²y + 7xy² → [Binomial]
5). 3x²y - 10x² → [Binomial]
6). 3x²y + 4x²y = 7x²y → [Monomial]
7). 3x²y + 3x³ → [Binomial]
Therefore, by adding 12x²y and 4x²y result will be a monomial.
