ok I need help so bad on this question and even this test but the question is

( 9m+6)+(-5m-6) and the answers are
4m+12
14m+12
14m-12
and 4m
please help I am very confused.

since a +1 is understood in front of each of the brackets of

( 9m+6)+(-5m-6) , that is, think of it as
1(9m+6) + 1(-5m-6) , just use the distributive property to get

9m + 6 - 5m - 6
= 4m + 0
= 4m

I can definitely help you with this question!

To simplify the expression (9m + 6) + (-5m - 6), you need to combine like terms. Like terms are terms that have the same variable(s) and exponent(s).

In this case, the like terms are 9m and -5m.

To combine these terms, you add or subtract their coefficients. In this case, the coefficient of 9m is 9, and the coefficient of -5m is -5.

So, 9m - 5m simplifies to 4m.

Now, let's simplify the constants 6 and -6.

To combine them, you add or subtract them. In this case, 6 - 6 equals 0.

Now, you can rewrite the simplified expression by combining these results:

4m + 0

Since anything added to zero remains the same, the expression further simplifies to just 4m.

Therefore, the answer to the expression (9m + 6) + (-5m - 6) is 4m.

To simplify the expression (9m + 6) + (-5m - 6), follow these steps:

1. Remove the parentheses:
9m + 6 - 5m - 6

2. Combine like terms:
(9m - 5m) + (6 - 6)
4m + 0

3. Remove the term with a coefficient of zero:
4m

Therefore, the simplified expression is 4m.
