A tire from Kevin's bicycle is shown below. Which is closest to the distance traveled, in inches, after 2 full rotations of the tire?

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

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.

Item 1 use the polygon tool to draw a rectangle with a length of 4 units and a height of 2 units. one of the sides of the rectangle falls on line ef , and the rectangle has a vertex of e. each segment on the grid represents 1 unit.
