The tile along the edge of a triangular community pool needs to be replaced.

A right triangles, where the hypotenuse is labeled 8 x squared, the height is labeled 4 x squared + 15, and the base is labeled 8 x + 10.
Which expression represents the total perimeter of the pool edge?

12x2 + 15
20x2 + 25
12x2 + 8x + 25
24x2 + 16x + 50

Perimeter = hypotenuse + height + base
= 8x^2 + (4x^2 + 15) + (8x + 10)
= 8x^2 + 4x^2 + 8x + 15 + 10
= 12x^2 + 8x + 25.

Answer: 12x^2 + 8x + 25.
