Simplify the expression below -3(10x+4y)+6(6x-2y)

6x-24y

Step-by-step explanation:

Apply order of operations as follows:

=-3(10x+4y)+6(6x-2y)

=-30x-12y+36x-12y

=6x-24y

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
