Answer:
14 1/2
Step-by-step explanation:
Rewriting our equation with parts separated
=7 + 7/8 + 6 + 5/8
Solving the whole number parts
7 + 6=13
Solving the fraction parts
7/8 + 5/8= 12/8
Reducing the fraction part, 12/8,
12/8=3/2
Simplifying the fraction part, 3/2,
3/2=1 1/2
Combining the whole and fraction parts
13 + 1 + 12=14 1/2
31
Area = 1/2 (Base*height)
558 = (1/2)(36*H)
1116=(36H)
Height = 31
you can check it by putting that back into the equation
C. 12x + 40
Got 100% on edge.
