find the moments of inertia ix, iy, i0 for a lamina that occupies the region d and has the given density function ������. d = {(x, y) | 1 ≤ x ≤ 3, 1 ≤ y ≤ 7}; ������(x, y) = ky2

Find the value of x for which the lines are parallel.

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
