evaluate: 12 + 7(-2h - 3) for h = -3

Explanation:

Step1: Expand the expression

$12 + 7(-2h - 3)=12-14h - 21$

Step2: Combine like - terms

$12-14h - 21=-14h+(12 - 21)=-14h - 9$

Step3: Substitute $h = - 3$

Substitute $h=-3$ into $-14h - 9$, we get $-14\times(-3)-9$.

Step4: Calculate the result

$-14\times(-3)-9 = 42-9=33$

Answer:

$33$
