The following table shows the length and width of a rectangle: Length Width Rectangle A 3x 2 2x − 1 Which expression is the resu
Stolb23 [73]

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.

P = 2 (L + W)

P = 2 ( 3x+2 + 2x-1)

P = 2 ( 5x +1)

P =10x +2

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.

What is the elimination of 20x+5y=120 and 10x+7.5=80
Grace [21]
20x+5y=120
10x+7.5y=80    multiply this one by 2
___________

20x+5y=120
20x+15y=160   subtract 

___________

        -10y=-40    divide both sides by -10 
____________

             y=4         

20x+5(4)=120   plug 4 in for y in the first equation 
20x+20=120     multiply 
20x=100           subtract 
x=5                   divide to find x
