Anybody know how to solve this step by step?

16 more than the product of 5 and p

What is the multiple zero and multiplicity of f(x) = (x ? 3)(x ? 3)(x + 5)? multiple zero is 3; multiplicity is 2 multiple zero is 5; multiplicity is 1 multiple zero is ? 5; multiplicity is 1 multiple zero is ? 3; multiplicity is 2

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?
