Serena has 3 necklaces, 6 pairs of earrings, and 4 bracelets in her jewelry box. how many different combinations of a necklace, a pair of earrings, and a bracelet can she wear?

4x and 6y

im not sure though

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

you can use a^2+ b^2=c^2
