10th grade geometry find the unknown length based on the given information lj is to jn as mk is to kp. lj = 8 , jn = ? , mk = 14 , kp = 6 . it's supposed to be set up like 8 over x = 14 over 6

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

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

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
