Write a real world problem that can be modeled by x-13> 20.

Alex and her friend were trying to find who had more pieces of candy. Her friend had 20. Alex had x but lost 13 of them. They found out that Alex had more.

So, x-13>20

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
