Explanation
For the given question, we are told to find the perimeter of the triangle
The perimeter of the triangle is the sum of all its three sides
So the perimeter will be:
[tex](2x+3)+(8x-4)+x^2[/tex]
Thus, we will have
[tex]\begin{gathered} =2x+3+8x-4+x^2 \\ =x^2+10x+3-4 \\ =x^2+10x-1 \end{gathered}[/tex]
Therefore, the answer is option C
