Mai is solving the equation (x-5)^{2}=0. She writes that the solutions are x=5 and x=-5.
Han looks at her work and disagrees. He says that only x=5 is a solution. Who do you agree with? Explain your reasoning.

The graph shows the number of square meters, A, covered by algae in a lake w weeks after it was first measured.
In a second lake, the number of square meters, B, covered by algae is defined by the equation B=975*(\frac{2}{5})^{w}, where is the number of weeks since it was first measured.
For which algae population is the area decreasing more rapidly? Explain how you know.
