Answer 3

Let me check your answer.

Answer 4

I will just show you the full process.

Answer 5

ok

Answer 6

Step One: Convert Subtraction into Addiition.\[2m^2~–~4n^2~+~3m~–~6m^2~–~2m~+~7n^2\]\[2m^2~+~-4n^2~+~3m~+~-6m2~+~-2m~+~7n^2\]Step Two: Combine Like Terms.\[2m^2~+~-6m^2~+~3m+~-2m~+~7n^2~+~-4n^2\]Step Three: Add and/or Subtract.

Answer 7

Do the adding/subtracting and tell me what answer you get. @TheAsker2002

Answer 8

All of it?

Answer 9

Yep.

Answer 10

Add this: \(2m^2~+~-6m^2~+~3m+~-2m~+~7n^2~+~-4n^2\)

Answer 11

24

Answer 12

Nope. What about the variables?

Answer 13

m n

Answer 14

Also, 24 is not one of your answers.

Answer 15
