Solve for k. 4k+3/6 + 4k-8/9 = 5k-4/3 - k-3/2

k = -4
k = -10
k = 44
k = 58

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
