Use the grouping method to factor this polynomial. x3 + 2x2 +7x+14
A. (x2 + 2)(x+8)
B. (x2 + 2)(x+7)
C. (x2 +7)(x+2)
D. (x2+8)(x+2)

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

4x and 6y

im not sure though

x = 23.78
