Brett Kirk · Answer 1

The answer is A.

Step-by-step explanation:

You have to add up both polynomials together:

A = 7x² + 3xy

B = - 3xy

A + B = 7x² + 3xy + (-3xy)

= 7x² + 3xy - 3xy

= 7x²

Let the polynomials A = 7x² + 3xy e B = - 3xy.Determine A + Ba) 7x²b) 3xyc) 7x² + 6xyd) 14x² + 6xye) - 3xy
