The formula for finding the perimeter of a triangle is as stated below;
Perimeter of a triangle = Sum of the three sides of the triangle
Let's assume that the three sides of the triangle are 23x + 14, 2x + 15, and 25x + 29, the expression for the perimeter of the triangle can be given as;
[tex]\begin{gathered} \text{Perimeter of the triangle }=(23x+14)+(2x+15)+(25x+29) \\ =50x+58 \end{gathered}[/tex]Therefore, the expression for the perimeter of the triangle with sides 23x + 14, 2x + 15, and 25x + 29 is;
Perimeter = 50x + 58
