The perimeter of a regular pentagon can be represented by the equation p=5s
where p is the perimeter and s is the length of a side.
does this equation represent a proportional relationship?

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
