Answer 2

It looks like you have two expressions that you'd like to simplify. Let's simplify each of them step by step:

1. Simplify the expression -12a - 25b + 18a + 14b:

   Combine like terms by adding or subtracting coefficients of similar variables:

   (-12a + 18a) + (-25b + 14b)

   6a - 11b

2. Simplify the expression -7(m - 4) + 5(m + 2):

   Distribute the constants (-7 and 5) into the parentheses:

   (-7 * m) - (-7 * 4) + (5 * m) + (5 * 2)

   -7m + 28 + 5m + 10

   Now, combine like terms by adding or subtracting coefficients of similar variables:

   (-7m + 5m) + (28 + 10)

   -2m + 38

So, the simplified expressions are:

1. -12a - 25b + 18a + 14b simplifies to 6a - 11b.
2. -7(m - 4) + 5(m + 2) simplifies to -2m + 38.
