A 7-pack of plastic cups costs $0.84. What is the unit price?

$0.12

Step-by-step explanation:

divide 0.84 by 7 to get the price per cup

$0.12

Step-by-step explanation:

First you must take 0.84 and divide it by 7.

Basically, your're just dividing your 0.84 into 7 groups.

0.84÷7= 0.12

So your answer/unit price is 0.12

I hope I was clear and concise.

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.
