A square with sides -6 units in length is reflected across the x-axis. How long are the sides in the reflected figure

Answer 1

The sides of the square in the reflected figure are also -6 units in length.

When a shape is reflected across the x-axis, the distance from the x-axis remains the same. Since the original square had sides of length -6 units, the reflected square will also have sides of length -6 units.
