If necessary, combine like terms. (5x+1)(5x-1)

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

Point q is equidistant from the sides of ∠tsr. find m∠rst.

Witch sequence shows a pattern where each term is 1.5 times the previous term
