Answer:

The sum is a binomial with a degree of 6

Step-by-step explanation:

we have

[tex](3x^{2}y^{2}-2xy^{5})+(-3x^{2}y^{2}+3x^{4}y)[/tex]

Group terms that contain the same variable

[tex](3x^{2}y^{2}-3x^{2}y^{2})-2xy^{5}+3x^{4}y[/tex]

[tex]0-2xy^{5}+3x^{4}y[/tex]

[tex]-2xy^{5}+3x^{4}y[/tex]

The sum is a binomial ( two terms) with a degree of 6  

[tex]-2xy^{5}[/tex] has a degree of 6 (x has an exponent of 1, y has 5, and 1+5=6)

The sum of the polynomial is a binomial with a degree of 6. The correct option is D) and this can be determined by using arithmetic operations.

Given :

Polynomials --   [tex]3x^2y^2-2xy^5[/tex] and [tex]-3x^2y^2+3x^4y[/tex]

The following steps can be used to determine the sum of the given polynomials:

Step 1 - Write the sum of the given polynomials.

[tex]3x^2y^2-2xy^5-3x^2y^2+3x^4y[/tex]

Step 2 - Subtract [tex]3x^2y^2[/tex] from [tex]3x^2y^2[/tex] in the above expression.

[tex]-2xy^5+3x^4y[/tex]

The above expression cannot be further simplified. Therefore, this is the final expression of the sum of the given polynomials.

The sum of the polynomial is a binomial with a degree of 6. Therefore, the correct option is D).
