The graph of y = x2 + 11x + 24 is equivalent to the graph of which equation?
a) y = (x + 8)(x + 3)
b) y = (x + 4)(x + 6)
c) y = (x + 9)(x + 2)
d) y = (x + 7)(x + 4)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
