3.56

Step-by-step explanation:

The fraction must equal 1 when simplified because 6.93 times 1= 6.93

Because 4.21 is found on both top and bottom, they get eliminated. So only 3.56 is left.

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

answer: c

(2, -4)

goes 7 to the

(9, 4)
