galben [10]

Answer: 15r^2-21r+5

Step-by-step explanation:

Given: Perimeter of triangular garden = 25r^2 - 9r + 14

The sum of two sides of the garden = 10r^2 + 12r + 9

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5

The expression represent the third side = 15r^2-21r+5.
