To factor the equation, first make sure the right hand side is equal to 0. Do this by subtracting 25 from both sides of the equation.
The equation becomes,
n^2-8n-9 = 0
Factoring the equation now gives you (n-9)(n+1) = 0.
In order to find the solutions to this equation, find values of 'n' that make the equation equal to 0.
In this case, if n is 9 or -1, we get the answer 0.
Proof: (9-9)(n+1) => (0)(n+1) = 0
or (n-9)(-1+1) => (n-9)(0) = 0.

Answer:
B
Step-by-step explanation:
At least means that the amount is at least be this much, but it could be more:greater than or equal to. Since the ship could only take a certain amount of passengers , the amount of passengers should be less than the limit or equal to the limit, but can't be over.
