HELP!
Each of two congruent sides of an isosceles triangle is 2n + 7 and the third side is 3n. write two equivalent expressions for the perimeter,also combine like terms to find the perimeter

Respuesta :

So one way we can do this is- 

2(2n+7)+3n=

4n+14+3n=

7n+14

Another simpler way possible is-

2n+7+2n+7+3n=

RE-ORDER

2n+2n+3n+7+7=

COMBINE LIKE TERMS

7n+14
