what is a function rule for the perimeter P of a building with a rectangular base if the width w is 2x the length l?

Answer 1

y=-10,for x=2

Answer 2

Usually, the width is shorter than the length. However, assuming that youa re correct in the width being twice the length.

Perimeter is 2l + 2w = P.
Since 2l = w, you can substitute w for 2l.
Giving w + 2w = P, so
3w = P.

Answer 3

39

Answer 4

If the width is 2L than 2L+2L+L+L than P=6L.
