Urgent: tim created a table that shows the cost of books in a bookstore. does this table shows a proportional relationship? * yes no

No

Step-by-step explanation:

You should write down all the numbers as simplified fractions to see if they are proportional

1/4 stays as 1/4

2/6 is simplified as 1/3

3/12 is simplified as 1/4

and 4 out of 18 is simplified as 2/9

Since the simplified fractions are not the same, it's not proportional :)

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.
