Final answer:

To find the value of x for a perimeter of 23, the equation 2x + 1 + 3x - 5 + 4x = 23 is set up and simplified to x = 3.

Step-by-step explanation:

The question asks to find the value of x when the perimeter is 23. The given expressions (2x+1, 3x-5, 4x) are likely to represent the lengths of the sides of a polygon. To find x, you would set up the equation for the perimeter:

2x + 1 + 3x - 5 + 4x = 23

Combine like terms to simplify the equation:

9x - 4 = 23

Add 4 to both sides to isolate the terms with x:

9x = 27

Divide both sides by 9 to solve for x:

x = 3

So, the value of x is 3 to achieve a perimeter of 23.

perimeter is the length of all sides added up so we add the expressions

(2x + 1) + (3x - 5) + (4x) = 9x-4

9x - 4 = 23

now work backwards

add 4 to 23 to get rid of -4

9x = 27

now divide by 9 to get x

x = 3
