The following table shows the length and width of a rectangle: Length Width Rectangle A 3x 2 2x − 1 Which expression is the result of the perimeter of rectangle A and demonstrates the closure property? 2x 2; the answer is a polynomial 2x 2; the answer may or may not be a polynomial 10x 2; the answer is a polynomial 10x 2; the answer may or may not be a polynomial.

Respuesta :

The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.

What is a perimeter?

A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.

Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.

[tex]P = 2 (L + W)[/tex]

[tex]P = 2 ( 3x+2 + 2x-1)[/tex]

[tex]P = 2 ( 5x +1)[/tex]

[tex]P =10x +2[/tex]

A polynomial function is a function that involves only positive integer exponents of a variable in an equation.

Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
