Rectangle abcd has a vertex coordinates a(1,-2) b(4,-2) c(4,-4) and d(1,-4) it is translated 1 unit to the left and 3 units up what are the coordinates of a

Find the value of the variable and the length of each secant segment.

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

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
