A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 7 of the large marbles are green, and 6 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is large or white?

Factor the polynomial, if possible. if the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75

Factor the gcf out of the polynomial 9x^6+6x^4+15x^3

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
