Answer:
C. 70 in^2
Step-by-step explanation:
What you do is use the formula for finding the area of a trapezoid.
A=a+b/2(h).
a=8
b=12
h=7
A=8+12/2(7)=70 in^2 is your answer.
It’s the second one x>_12 because it’s a closed circle on the number line and it’s going right
5.5 in fraction is 5 1/2
hope that helps :)
