Which statements are true about the polynomial 28vw + 49v + 35w? check all that apply. the coefficients have no common factors other than 1. there are no common variables among all three terms. the gcf of the polynomial is 7v. each term written as the product, where one factor is the gcf, is 7(28vw) + 7(49v) + 35(w). the resulting expression when factoring out the gcf is 7(4vw + 7v + 5w).
