Answer:

P = 7x^2 + 2x + 7

Step-by-step explanation:

The perimeter is the sum of the lengths of the three sides of the triangle:

P = 2x^2 + 4 + 5x^2 - 6x + 8x + 3.

Group and combine like terms:

P = 2x^2 + 5x^2  + 4 + 3 - 6x + 8x, or:

P = 7x^2 + 2x + 7

The perimeter of the triangle is [tex]7x^2 + 2x + 7[/tex].

Given that,

  • The sides of a triangle are represented by the expressions  i.e. [tex]2x^2 + 4, 5x^2 - 6x[/tex], and 8x + 3.

Based on the above information, the calculation is as follows:

[tex]= 2x^2 + 4 + 5x^2 - 6x + 8x + 3[/tex]

= [tex]7x^2 + 2x + 7[/tex]

Therefore we can conclude that the perimeter of the triangle is [tex]7x^2 + 2x + 7[/tex].
