determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2
A because it start at 20 and divided 1/2 each time. And when you solved 2/ 1/2 , you get 4 and that is correct because you have 4 arrows.
Answer:
You need to find the volume in two parts then add them together, think of the shed as box and a rectangular prism.
Volumebox=length x width x height
Volumeprism=1/2 x base of triangle x height of triangle x length
