To show that −3(−13+m)+11 is equivalent to −3⋅m+12, we'll follow the given steps:

1. Apply the Distributive Property:
-3(−13+m) + 11 = -3 * -13 + (-3 * m) + 11

2. Apply the Inverse Property of Multiplication:
-3 * -13 + (-3 * m) + 11 = 39 + (-3 * m) + 11

3. Apply the Commutative Property of Addition and add:
39 + (-3 * m) + 11 = (-3 * m) + 39 + 11

4. Simplify:
(-3 * m) + 39 + 11 = -3 * m + 50

Therefore, −3(−13+m)+11 is equivalent to −3⋅m+12.
