6m^2n^2 - 3mn + 4mn + 13m^2n^2 + 9
combine like terms
19m^2n^2 + mn + 9 <==
Answer:
10x^2 +2x -9
Step-by-step explanation:
Group things that are alike and simplify
(3x^2+7x^2) = 10x^2
(2x) nothing to add or subtract with it so it stays positive 2x= +2x
(-5-4) = -9
Then put the answer from highest degree to lowest
It's the one on the top righr, -2/9 w + 2/15.
Your answer should be: a solution
