Kim packed 6 boxes with school supplies. Each box contained an equivalent number of pencils, pens, and rulers. Which list of school supplies could be the greatest number of pencils, pens, and rulers that Kim packed into boxes?

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
