Which is a description of the polygon

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples ofpolygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.

Step-by-step explanation:

A plane shape

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
