Which expression represents the distance between point (0, a) and point (a, 0) on a coordinate grid?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Order the measurements from the least to the greatest. 2,720 ml , 24.91 l , 0.0268 kl

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
