Edgar is making an open-top box from an 12 cm x 16 cm sheet of paper. The volume v(x) is a function of the side length of the square cutout x.


Which expression represents v(x)?

V(x) = (12 - 2x)(16 - 2x)x

V(x) = (12 - x)(16 - x)x

V(x) = 2x(12 - 2x)(16 - 2x)

V(x) = 2x(12 - x)(16 - x)

Allen is making an open-top box from a 50 mm x 32 mm sheet of paper. The volume v(x) is a function of the side length of the square cutout x.


Which expression represents v(x)?

V(x) = (50 - 2x)(32 - 2x)x

V(x) = (50 - x)(32 - x)x

V(x) = (25 - 2x)(16 - 2x)x

V(x) = (25 - x)(16 - x)x

Poe is making an open-top box from a 17 inch x 24 inch sheet of paper. The volume v(x) is a function of the side length of the square cutout x.


Which expression represents v(x)?

V(x) = (24 - 2x)(17 - 2x)x

V(x) = (17 - x)(24 - x)x

V(x) = (8.5 - 2x)(12 - 2x)x

V(x) = 2x(24 - 2x)(17 - 2x)
