SOLUTION: "x" varies direcly as the square of "s" and inversely as "t". How does "x" change when "s" is doubled? When both "s" and "t" are doubled? I figured "x" = "k" "s"

Question 19232: "x" varies direcly as the square of "s" and inversely as "t". How does "x" change when "s" is doubled? When both "s" and "t" are doubled?
I figured "x" = "k" "s" squared divided by "t" (using "k" as a non zero constant but I'm stuck.

Try this:
Multipy s by 2.
= So, x is quadrupled when s is doubled.
Multiply s and t by 2.

= So, x is doubled when both s and t are doubled.
