Answer both question

5.)

15.36+x=32.11

15.36+x-15.36=32.11-15.36

x=32.11-15.36

x=16.75

6.)

-2(a-3b+c)

-2a+6b-2c

7.)

3a+15y-5a=-a+2(3-a)

-2a+15y= -a+6-2a

-2a+15y=-3a+6

-2a+15y+2a=-3a+6+2a

15y=-a+6

15y/15=-a+6/15

y=-a+6/15

I hope this is good enough:

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
