Ln which quadrant is the point (–3, 5) located? quadrant I quadrant II quadrant III quadrant IV

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

Someone me what is the area of this figure? 18m 18m 8m 16m

How can you find the mean absolute deviation (mad) for this set of data?
