The length of each of the two congruent sides of an isoscleses triangle is 2n+7 and the length of the third side is 3n. Draw and label the triangle. Then write two equivalent expressions for its length of the perimeter.

Respuesta :

To find the perimeter you add together the length of all sides. Therefore,

1). 2n + 7 + 2n + 7 + 3n = perimeter

2). 2(2n + 7) + 3n = perimeter
