would you use the same method to find the eighth partial sum as you used to find the fifth partial sum? why or why not

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

Quadrilateral abcd in the figure below represents a scaled-down model of a walkway around a historic site. quadrilateral efgh represents the actual walkway. abcd is similar to efgh. what is the total length, in feet of the actual walkway?

1yd 1 ft = 1 1/12 1 1/3 1 1/2 1 1/6
