A postcard has an area of 10 square inches. Two enlargements of the postcard have areas of 40 square inches and 160 square inches. In each postcard, the length is 2 1/2 times the width.

Which of the following could be the dimensions of the postcard or one of the enlargements? Mark all that apply.

A 4 inches by 20 inches

B 8 inches by 20 inches

C 4 inches by 10 inches

D 2 inches by 5 inches

E 5 inches by 8 inches

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
