Answer 1

15x + 18

Explanation:

To find the perimeter add all the sides of the triangle.

2x + 8 + 13x - 1 + 11 = 15x + 18

Answer 2

15x + 18

Explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside. Therefore, the perimeter of a triangle is the sum of its three side lengths.

From inspection of the given triangle, the three side lengths are:

• 
  `2x + 8`
• 
  `11`
• 
  `13x - 1`

To determine the expression for the perimeter, we can sum the side lengths:

`\begin{aligned}\textsf{Perimeter}&=2x+8+11+13x-1\\&=13x+2x+11+8-1\\&=15x+11+8-1\\&=15x+19-1\\&=15x+18\end{aligned}`

Therefore, the simplified expression for the perimeter of the given triangle is:

`\large\boxed{\boxed{15x+18}}`
