3) A teacher plans to buy books for her class. She has 24 students and wants to buy a book for each one of them. The books cost $4
each for softcovers and $6 each for hardcovers. The teacher has
$120 to spend. How many of each type of book can she buy?

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.

the radius is 2 times the diameter.
