Answer:

[tex]\textsf{Perimeter}=x^2+10x-1[/tex]

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Given sides of a triangle:

  • [tex]2x + 3[/tex]
  • [tex]8x - 4[/tex]
  • [tex]x^2[/tex]

Therefore, to find the perimeter of the triangle, sum the given sides:

[tex]\begin{aligned}\sf Perimeter & = (2x+3)+(8x-4)+x^2\\& = 2x+3+8x-4+x^2\\& = x^2 + 2x+8x+3-4\\& = x^2+10x-1\end{aligned}[/tex]

Perimeter=

  • Sum of sides
  • x²+2x+3+8x-4
  • x²+2x+8x+3-4
  • x²+10x-1
