The base of a pyramid is a square whose perimeter is 936936 m. what is the length of each side of this square?

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left

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

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x
