Answer:
C. 586.2 cm²
Step-by-step explanation:
Area of the figure = area of triangle + area of rectangle + area of semicircle
= (½*b*h) + (L*W) + ½(πr²)
Where,
b = 18 cm
h = 7 cm
L = 22 cm
W = 18 cm
π = 3.14
r = ½(18) = 9 cm
Substitute
Area = (½*18*7) + (22*18) + ½(3.14*9²)
Area = 63 + 396 + 127.17
Area = 586.17 ≈ 586.2 cm²
Answer:
first we get y on one side by itself.
4x+5y=5
we'll move x to the other side.
4x-4x+5y=5-4x
simplify.
5y=5-4x
now we get rid of the coefficient on y.
5y/5=(5-4x)/5
simplify.
y=5/5-4x/5
y=1- 
The answer is 
A storage tank. I hope this helps ^^
The answer would be 24/x+3 in Polynomial Division :-)
