Because of your favorite lemonade it is $3.84 for 3 gallons. write this as an unit rate

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
