Find the surface area of the triangular prism

In simplified exponential notation, the expression a^2•a^-3•a 1/a 0

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

Find the equation of the line with slope =8 and passing through (6,53) write your equation in the form y=mx+b
