Acertain panel is to be composed of exactly three women and exactly two men, chosen from x women and y men. how many different panels can be formed with these constraints? (1) if two more women were available for selection, exactly 56 different groups of three women could be selected. (2) x = y + 1 16. if x > y, x² – 2xy + y² – 9 = 0, and x + y = 15, what is x?
