A carpenter purchased 60 ft of redwood and 70 ft of pine for a total cost of $289. A second purchase, at the same prices, included 100 ft of redwood and 60 ft of pine for a total cost of $408. Find the cost per foot of redwood and of pine.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
