The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>What is a perimeter?</h3>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.
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.

Answer:
4th option
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= - (3x² - 3x - 5)
= 4x² - 3x² + 3x + 5 ← collect like terms
= x² + 3x + 5
