Please help me answer 1-10 please I really need it now and please actually answer the question !!!

Which is the completely factored from of xy^3-x^3y

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2
