Find the number of positive three-digit even integers whose digits are among 9, 8, 7,5, 3, and 1.

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles
