Question

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

Answer 1

P=2(2n+7)+3n

p=4n+14+3n

p=7n+14

p=7(n+2)

Answer 2

The perimeter of your isosceles triangle is equal to 7n+14 by combining like terms.

Hope this helps
