Step-by-step explanation:
A semicircle is a half circle. That means a semicircle will have half of the area of a circle. You might think that means it will have half the perimeter of a circle, but that is not true.

Answer:
B. 4x^2=28x-112=0.
Step-by-step explanation:
Using area=length*width, 160=(2x+8)(2x+6).
Expanding, (2x+8)(2x+6)=4x^2+16x+12x+48.
Setting this equal to 160, 160=4x^2+28x+48, or 4x^2+28x-112=0.
Answer:
x -7
Step-by-step explanation:
f(x)=-3x-5
g(x)=4x-2
(f+g)(x)= -3x-5+4x-2
Combine like terms
= -3x+4x -5-2
= x -7
