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.
