What is 3/8 in simplest form

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 sin(x) = 0 and cos(x) = 1, what is tan(x)?

What three-dimensional solid have 6 rectangular faces, 2 equal bases that are not rectangles and 18 edges
