Simplify the expression (9m-3) - (2m+12) (1 point) Responses 18m2−36 18 m squared minus 36 7m - 15 7m - 15 7m+9 7m+9 11m - 15

Answer 1

To simplify the expression $(9m-3)-(2m+12)$, follow these steps:

1. Distribute the negative sign through the second parentheses: $$(9m-3)-(2m+12)=9m-3-2m-12$$

2. Combine like terms:

   • For the $m$ terms: $9m-2m=7m$
   • For the constant terms: $-3-12=-15$

Putting it all together, we have: $$7m-15$$

Thus, the simplified expression is $\boxed{{\displaystyle 7m-15}}$.
