12.5 = 3x = 20
what is the solution to the equation?

a. x = 1.3
b. x = 2.5
c. x = 7.5
d. x = 10.8

okay so 15.15 *()5: +5/6

step-by-step explanation:

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

answer: -8.2562234e+13
