Andrew answered the following inequality, his work is shown below:
−5x − 7 ≤ − 52
−5x ≤ −45
x ≤ 9
What mistake did he make?
A. He should have added 7 to both sides in the first step.
B. He should have flipped the symbol in the last step.
C. He should have divided both sides by -5 in the first step.
D. He should have divided negative 45 by negative 5 and gotten -9.

A = area of triangle + area of rectangular + half of the circle area

triangle area = 1/2 × base × height

triangle area = 1/2 × 3 × 5 = 15/2 = 7.50

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

rectangular area = length × width

rectangular area = 6 × 5 = 30

circle half area = 1/2 × pi × radius^2

circle half area = 1/2 × 3.14 × 3^2

circle half area = 1.57 × 9

circle half area = 14.13

A = 7.50 + 30 + 14.13

A = 51.63 m^2
