Anumber is said to be a perfect square if it can be written as an integer squared, and a perfect cube if it can be written as an integer cubed. for example, four is a perfect square (2²), and eight is a perfect cube (2³). the number one is both a perfect square and a perfect cube. what’s the next smallest number that is both a perfect square and perfect cube?

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
