What is a polygon? a. a geometric shape with three or more sides b. a circular geometric shape c. a piece of embroidered fabric d. a point on a bezier curve select the best answer from the choices provided a b c d

 The correct option is

(A)  A geometric shape with three or more sides.

Step-by-step explanation:  We are given to select the best definition of a polygon.

We know that

a polygon is a geometric shape having number of sides greater than or equal to three.

For example,

(a) A triangle is a polygon having three sides.

(b) A quadrilateral is a polygon having four sides.

(c) A pentagon is a polygon having five sides.

Three polygons, a triangle, a quadrilateral and a pentagon are shown in the attached figure below.

Thus, option (A) is CORRECT.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
