Jacks bank statement shows an account balance of -$25.50. which describes the magnitude, of size, of the debt in dollars

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

Table which ratio is equivalent to 3: 7? 6: 7 3: 21 24: 56 15: 30
