Answer:
236.715 ft²
Step-by-step explanation:
The figure consists of the rectangle with sides 15 ft and 4 ft and two semicircles with diameter 15 ft (radius 7.5 ft).
The area of the rectangle is
A₁=15·4=60 ft²
The area of two semicircles together is the area of circle. Thus,
A₂=πr²=π·7.5²=56.25π≈176.715 ft²
The area of the figure is
A=A₁+A₂=60+176.715=236.715 ft²
Y when x=0: 3

Answer:
(x+1)(x-9)
Step-by-step explanation:
x^2+x-9x-9=0
x*(x+1)-9(x+1)=0
(x+1)(x-9)=0
x+1=0
x-9=0
x=-1 and x=9
