The expression is:
-2(1.5h + 5) - 4(0.5 + 3h)
Expanding the first parentheses:
-2(1.5h + 5) = -3h - 10
Expanding the second parentheses:
-4(0.5 + 3h) = -2 - 12h
Substituting the expanded parentheses into the original expression:
-3h - 10 - 2 - 12h = -15h - 12
So the simplified expression is:
-15h - 12
