Answer:
equation: a/.5b=h
h=9
Step-by-step explanation:
a=1/2bh
divide both sides by 1/2b to get h alone
a/.5b=h
a/.5b=h
54/0.5(12)=h
54/6=h
9=h
Answer:
-8i + 12

Solve (-4 + -6) first, as this is in parentheses:


Solve 5.3 * -10 next, as this is multiplication:


Now we can solve the equation:

The answer is 63.
