Use the triangle below and the given trigonometric ratio to determine which angle in the triangle below is tan a = 7.5/18

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

Solve the equation - 2(m -30) = -6m a-15 b-13 c-8 d8
