If the universal set U = {2, 4, 6, 8, 10) and F = {4,10), t hen F'is A ? {1,3,5,7,9)
B. ? ] {2.6.8)
c. ? | [4.6.8.10)
? (5.7.9)

B is the answer

f' means all the other elements in the universal set except the elements in F

so the answer is 2,6,8

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
