Question

The legs of a scalene triangle are represented by (x + 4), (x + 8), and ( 2x − 3). Which polynomial expression BEST represents the perimeter of the triangle?

Answer 1

perimeter = x + 4 + x + 8 + 2x - 3
= 4x + 9

Answer 2

`(4x+9)`

Explanation:

we know that

The perimeter of triangle is equal to the sum of the three length sides

therefore

`P=(x+4)+(x+8)+(2x-3)\\ \\P=(x+x+2x)+(4+8-3)\\ \\P=(4x+9)\ units`
