Mr. Nguyen is drawing a rectangle. The width of the rectangle is 2 1/2 less than 1/4 times the length. The perimeter of the rectangle is 23 inches. What is the length of the border

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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.
