11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)

If it is: 13m+5n-6m+9n Then simplified it is: 7m+14n

4n - 5n is biger and no it not

depends on what is imbetween all of those numbers and variables. If it as all + or all - or wat! But pretty much it just means to show your work! lets say the problem is 5n+4+9n times 5n - 20 +9n you just show your work follow the Order of Operations though 9n times 5n= 45n problem= 5n+4+45n-20+9n add alike terms and variables 5n+45n+9n= 59n 4-20= -16 problem= 59n-16 and that's as far as you can go for now

The forces are in opposite directions, so subtract. 9n - 5n = 4n. Direction is North.

5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.

-5 plus 9n plus 6 is 1 plus 9n.

5m-5n+5m+5n When simplified: 10m

9n + n = 10n

8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n

9n + 18 = 81 9n = 63 n = 7

3n+5n=8n
