Shaniqua correctly finds the closest benchmarks for three numbers.

Three-sevenths is closest to the benchmark One-half
StartFraction 5 over 21 EndFraction is closest to the benchmark 0
0.87 is closest to the benchmark 1

Which shows the numbers Three-sevenths, StartFraction 5 over 21 EndFraction, and 0.87 in order from greatest to least?

StartFraction 5 over 21 EndFraction, 0.87, Three-sevenths

StartFraction 5 over 21 EndFraction, Three-sevenths, 0.87

0.87, StartFraction 5 over 21 EndFraction, Three-sevenths

0.87, Three-sevenths, StartFraction 5 over 21 EndFraction

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.
