Question

The sides of a triangle are (x2 + 5x - 2), (5x2 + 9x + 5), (2x2 + 6). Find the perimeter of the given triangle.​

Answer 1

Answer: 8x^2+14x+9

Step-by-step explanation:

As perimeter is the sum of all sides of a triangle then,

x^2+5x-2+5x^2+9x+5+2x^2+6

x^2+5x^2+2x^2+5x+9x+5+6-2

8x^2+14x+9
