anonymous one year ago What is true about the completely simplified sum of the polynomials 3x2y2 − 2xy5 and −3x2y2 + 3x4y? The sum is a trinomial with a degree of 5. The sum is a trinomial with a degree of 6. The sum is a binomial with a degree of 5. The sum is a binomial with a degree of 6.

there is your sum \[3x^2y^2 − 2xy^5+(−3x^2y^2 + 3x^4y)\] release the brackets \[3x^2y^2 − 2xy^5-3x^2y^2 + 3x^4y)\] combine like terms now

terms 3x2y2 and -3x2y2 make up 0. So there are left \[3x^4y-2xy^5\]

so a b c or d

now lets see on our binominal (Binominal is polynomial with two terms) the degree of our binomial is 6, since 5+1=6.

d
