2x +100=16+4x
-2x. -2x
100=16+2x
-16. -16
84=2x
divide both sides
x=42
Find the area of the total circle and when you find that area, multiply it by 145/360 for that is how much of the circle that area is.
Area of circle, 
r^2 and 13.69 times 3.14 is 42.9866. Then multiply by 145/360 to get about 17.3 inches squared.
Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...
x² + 6x - 24 = 0
Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132
x = -6 +/- √132 x' = -3 + √33
<span> -------------- /
2 \
x'' = - 3 - </span>√33
The correct answer is the letter D
I hope this help =)
