Answer:
10x + 3y^2 +6y + 7
Step-by-step explanation:
This is asking you to combine like terms.
First, order your expression to where like variables are together.
2x + 8x + 3y^2 + 6y + 5 + 2
Now, add like terms together. Variables of the same power can be combined.
2x + 8x = 10x
5 + 2 = 7
10x + 3y^2 +6y + 7
