Find the gcf of 20x^2y and 16xy^2 i believe it is 2xy^2 correct me if im wrong

4xy

Step-by-step explanation:

20x^2 y  = 4*5 x^2 y = 2*2*5*x*x*y

16*x*y^2 = 4*4*x*y^2 = 2*2*2*2*x*y*y

what is common in both

2*2*x*y

4xy

b

step-by-step explanation:

ez

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
