What is the value of x? x+45=11 enter your answer in the box in simplest form.

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Subtract 45 from both sides

x + 45 (-45) = 11 (-45)

x = 11 - 45

x = -34

-34 is your answer

hope this helps

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

b, i believe, but not sure.
