Ms. Chang's class decides to use the Cool Tee's company to make their T-shirts. The following equation represents the relationship
between the cost and the number of T-shirts n.
C = 2n + 20
a. The class wants to buy 25 T-shirts from Cool Tee's. Describe how
you can use a table and a graph to find the cost for 25 T-shirts

step-by-step explanation:

i am not sure sorry : c

the answer is a

step-by-step explanation:

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.
