You can put this solution on YOUR website! A triangle has 3 sides,3x + 7,4x - 9, and 5x + 6. find the expression that represents its perimeter.
Solution:
We know that the perimeter of the any polygon is given by the sum of all its sides. Here the sides of the triangle is given by:
3x + 7, 4x - 9 and 5x + 6
So adding all these sides, we get:
3x + 7 + 4x - 9 + 5x + 6
==> 3x + 4x + 5x + 7 - 9 + 6
==> 12x + 4
Hence, the perimeter of the triangle is given by 12x + 4
Hence, the solution.
