Which of the following expression(s) are fourth-degree trinomials? Select all that apply.

A.
3x^2y + 5x^3y + 6y^4
B.
6y^4 + 5x^3 + 1
C.
5xy − 5x^2y^2 + 7
D.
3y^3 + 3x^3y^3

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
