What are the solutions to the equation in the picture

a. x = −2,3

b. x = −1.871, 1.871

c. x = −1.871, 0

d. x = 0, 2.236

C.

Step-by-step explanation:

I think that's right.

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
