the tile along the edge of a triangular community pool needs to be replaced. which expression represents the total perimeter of the pool edge? 4x² + 15 pool 8x + 10 8x² 12x² + 15 20x² + 25 12x² + 8x + 25 24x² + 16x + 50

Answer

Answer:

C. $12x^{2}+8x + 25$

Explanation:

Step1: Recall perimeter formula

Perimeter of a triangle is sum of side - lengths.

Step2: Identify side - lengths

The side - lengths of the triangle are $4x^{2}+15$, $8x + 10$, and $8x^{2}$.

Step3: Add side - lengths

$(4x^{2}+15)+(8x + 10)+8x^{2}$.

Step4: Combine like terms

$(4x^{2}+8x^{2})+8x+(15 + 10)=12x^{2}+8x + 25$.
