Answer:

s₃ = 4n² - 6

Explanation:

The perimeter is the sum of the three sides. The unknown side will be a variable expression.

Perimeter = s₁ + s₂ + s₃

s₃ = Perimeter - s₁ - s₂

s₃ = (-6n² - 2) - (-8n² + 2) - (-2n² + 2)

s₃ = -6n² - 2 + 8n² - 2 + 2n² - 2

s₃ = 4n² - 6

You can check this by summing s₁, s₂, and s₃ and you should get the given perimeter as your answer.
