Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Explain how you can use the associative property to evaluate (7x50)x4.

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
