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
when it tells you what R is then you show a number line with -4 less then R
For this question, you would have to use the midpoint formula.
(X1 +X2 / 2 , Y1 + Y2 / 2)
In other words,
(9 + -3 / 2 , -7 +5 / 2)
(6 / 2 , -2 / 2)
(3 , -1)
Your midpoint is (3, -1)
