Paulita is going to build a storage cube. Each edge is 14 inches. The wood costs $0.03 per square inch. Use 0.03(5e2) , where e is the edge length, to evaluate for e = 14 . (1 point)

Answer 1

To evaluate for e = 14, we substitute 14 for e in the expression 0.03(5e^2):

0.03(5(14)^2) = 0.03(5(196)) = 0.03(980) = 29.4

Therefore, the expression evaluates to 29.4.

Answer 2

Miss Yang has bulletin boards of different sizes in her classroom. She wants to calculate how much border she needs for each one. The length of each bulletin board is 6 inches less than three times its width, w . Simplify w + 3w − 6 + w + 3w − 6 to find the formula for the perimeter of each of Miss Yang’s bulletin boards.(1 point) Responses 6w2 − 10 6 w squared minus 10

Answer 3

To find the formula for the perimeter of each bulletin board, we need to simplify the expression w + 3w - 6 + w + 3w - 6:

This simplifies to 10w - 12.

Therefore, the formula for the perimeter of each bulletin board is 10w - 12.
