The square prism has a base length of 2 ft. Which describes the cross section of the prism that is perpendicular to the base?
a rectangle with two 12-ft sides and two 2-ft sides
a rectangle with two 12-ft sides and two sides that are shorter than 2ft

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
