Point M is the midpoint of AB AM = 2x +9, and AB= 82 – 50.
What is the length of AM ?

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

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

4x and 6y

im not sure though
