Nope, kagari is right just use the spelled-out answers, not the letters :)
Not 100% i got a 60%

To add or subtract polynomials, you need to combine like terms. Like terms are terms that have the same variable(s) raised to the same exponent(s).
Let's simplify the expression (9m+6)+(-5m-6) step by step:
1. Distribute the negative sign to the terms inside the parentheses:
(9m + 6) + (-5m - 6) = 9m + 6 - 5m - 6
2. Group the like terms together:
(9m - 5m) + (6 - 6) = 4m + 0
3. Simplify the expression:
4m + 0 = 4m
So, the simplified answer is 4m.
collect like terms (same variable, if any)
make liberal use of the commutative property and distributive property
9m+6-5m-6
9m-5m +6-6
(9-5)m + 0
4m
Kagari is right except for 3 and 4,
