The base system costs $395. adding a subwoofer is an additional $89. two extra rear speakers are $75 each. and upgrading to a six-cd disk changer is an additional $225. round each amount to the nearest hundred dollars to find a reasonable estimate for the total cost of the new sound system.

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 answer is two. hope this !

probably the last option
