Twice "a" increased by the cube of "a" equals b.
translate into an equation or formula

Step-by-step explanation:

Let's do it part by part:

Twice "a":

This means 2 times a, or 2*a

Cube of "a":

This means a cubed, so a to the power 3, or

Also note "is" means "equal" and "of" means "multiplication.

Twice a increased by cube of a means both parts are summed so we have:

\

This is the formula/equation

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
