i need help with my math problem: x varies directly as the square of s and inversely as t. how does x change when s is doubled? when both x and t are doubled?

  1. x = A s^2/t
    A is a constant

    If s doubles and t stays the same, x increases by a factor of 4.

    In your last question, do you mean s and t are doubled, or x and t ?

    In either case, use the formula.
