The 3rd or 1st one I'm not sure which one but u have an idea of what it might be
Answer:
(a)31.42 inches
(b)942.48 Square Inches
Step-by-step explanation:
Given a sector of a circle with the following dimensions:
Radius of the circle =60 inches
Central Angle of the sector =30°
(a)Arc Length
Arc Length 

(b)Area of the sector
Area of the sector 

You would divide -204 divide it by -17 and you would get 12
X=12
30% of 50,400 = 30240.
Therefore the percentage loss is 30% over the course of 3 years.
-5x(x+3)-7(x-3)/x^2-9= -5x^2-15x-7x+21/x^2-9= -5x^2-22x+21/x62-9
