Best ResponseYou've already chosen the best response.0well from the last person who tried to help totally confused me ~ but i asked my teacher to but she made my confusion worse this is what she said. Let CD = x9 6/x = (x9)/6 cross multiply 36 = x^2  9x x^2  9x  36 When you factor this you will get 2 binomials. Set each equal to 0 and solve. Only the positive answer will work. Then set up another proportion with 9/y = y/answer for x

Best ResponseYou've already chosen the best response.1Yeah, it is using formulas you already use in a more complex way, but you don't have to memorize a new formula. That's why I like it. :)
