3. you purchase a car using a $25,000 loan with a 5% simple interest rate.

(a) suppose you pay the loan off after 4 years. how much interest do you pay on your loan? show your work.
(b) suppose you pay the loan off after 2 years. how much interest do you save by paying the loan off sooner? show your work.

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.
