What is true about the completely simplified sum of the polynomials 3x2y2 - 2xy5 and - 3x2y2 + 3x4y?

a) The sum is a trinomial with a degree of 5.

b) The sum is a trinomial with a degree of 6.

c) The sum is a binomial with a degree of 5.

d) The sum is a binomial with a degree of 6.

Add the polynomials

3x^2y^2 - 2xy^5 + (-3x^2y^2 + 3x^4y)

= 3x^2y^2 - 2xy^5 - 3x^2y^2 + 3x^4y

= 3x^4y - 2xy^5

The polynomial that has two terms is a Binomial.

The sum of exponents of first term is 5.

The sum of exponents of second term is 6.

Thus, the degree of simplified sum is 6.

D) The sum is a binomial with a degree of 6.
