Answer:

The option " The sum has degree of 6 , but the difference has a degree of 7 " is correct.

Step-by-step explanation:

Given that the sum and difference of the polynomials 3x^5y-2x^3y^4-7xy^3 and -8x^5y+2x^3y^4+xy^3

<h3>Now sum the given polynomials :</h3>

3x^5y-2x^3y^4-7xy^3+(-8x^5y+2x^3y^4+xy^3)

=3x^5y-2x^3y^4-7xy^3-8x^5y+2x^3y^4+xy^3

=-5x^5y+0-6xy^3

=-5x^5y-6xy^3

Therefore 3x^5y-2x^3y^4-7xy^3+(-8x^5y+2x^3y^4+xy^3)=-5x^5y-6xy^3

In the simplified <u>sum of the polynomials</u> -5x^5y-6xy^3  we have <u>the degree is 6</u>

<h3>Now difference the polynomials </h3>

3x^5y-2x^3y^4-7xy^3-(-8x^5y+2x^3y^4+xy^3)

=3x^5y-2x^3y^4-7xy^3+8x^5y-2x^3y^4-xy^3

=11x^5y-4x^3y^4-8xy^3

Therefore 3x^5y-2x^3y^4-7xy^3-(-8x^5y+2x^3y^4+xy^3)=11x^5y-4x^3y^4-8xy^3

In the simplified <u>difference of polynomials</u> 11x^5y-4x^3y^4-8xy^3 we have <u>the degree is 7</u>

Therefore the option " The sum has degree of 6 , but the difference has a degree of 7 " is correct

125 minutes, or 2 hours and 5 minutes.

\frac{5}7 = \frac{x}{175}
cross multiply
5*175=7x
875=7x
\frac{875}7=x
125=x
