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 \(\boxed{7m - 15}\).
