I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation

P = 2/5
P = 0.4
18k i believe because it is a varible and a number so when u multiply them u just put them together.... is this multi choice question because to see the answers would help
