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.

To know more about the perimeter, follow the link given below.

How do you find the lease common fatcor
8_murik_8 [283]

Answer:

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Combine like terms to simplify the expression:<br><br> -7x + 3y - 2 + 6x - 1 - y2
diamong [38]
It seems that the expression is - 7x + 3y - 2 + 6x -1 - y^2

like terms:

-7x + 6x = - x

3y stands alone

-2 - 1 = -3

- y^2 stands alone

Answer: - x + 3y - 3 - y^2

[note: if the last term is not y^2 but 2y, then you have to combine +3y - 2y = y and the answer would be - x + y - 3]

What’s the area<br> A. 64<br> B. 44<br> C. 30.25<br> D. 13.75
dalvyx [7]

Answer:

B) 44

Step-by-step explanation:

Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:

2.5*5.5=<u>13.75</u>

Then to solve for the square, it is also (B*H):

5.5*5.5=<u>30.25</u>

At this point, to solve for the total area, you just add the areas together:

13.75+30.25=<u>44</u>

<u />

Hope this helps!
