What does x= if the question is x over 1.2 =-7

Multiplying an even number of negative numbers gives an answer that is choose from:

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

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
