Which of the following is an example of parallel lines?                 a.        b.        c.        d.  

What is the upper quartile in the box plot?

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

The square root of 9x plus 7 plus the square rot of 2x equall to 7
