Question 184083: Not sure if this question goes here, but I am having a horrible time trying to figure this out, so any help is greatly appreciated. Thank you.
The perimeter of a triangular dog pen has one side represented by 3x, another side represented by x +19 and the third side represented by 2x + 6. Find the algebraic expression for the perimeter. Find the numerical perimeter if the value of x is 5 feet.

The perimeter is the sum of the triangles sides.
Perimeter+=+3x+%2B+%28x%2B19%29+%2B+%282x+%2B6%29
Perimeter+=+6x+%2B+25
If x = 5, then
Perimeter+=+6%2A5+%2B+25
Perimeter+=+30+%2B+25
Perimeter+=+55 feet
