The perimeter of a triangle is 78'. The lengths of the sides are represented by 3 conscutive integers. What are those lengths. I have no idea where to start with this one?????????? Thanks in advance!

The lengths of the sides are represented by 3 conscutive integers. Therefore, the sum of the lengths of the sides (Perimeter) is: P is given, so solve for n.
Hint: let the length of this triangle be (you may these choose this concecutive number to be as well). The second choice give you a nicer computation.
Still a bit confused on this one, I came up with an answer of P= 78 consecutive numbers are 25,26,27 but I am not sure how to put this as an equation.

I guess what I am asking is my final answer is going to look like this..... 78= 25+(26+1)+(27+2) That just does not look right.

That makes sense now...I see what I did. Thanks for all your help!!
