Mariam spends $200 at a jewelry shop . She spends $64 on rings & the rest on 4 equally priced bracelets which equation represents the scenario

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

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

Can you me find the missing length. i attached an image.
