There is no limit to the number of variables a formula can have.

It can represent formulas like A=L×W etc...
Because mathematical formulas can only describe dynamic changes if some elements (variables) vary in relation to other variables.
By inserting the known quantities into their respective variables.
The technique is known as algebra.
The formulas vary in what variables are related. Therefore it is sometimes useful to use one of the formulas, sometimes another, depending on what you know.
V=IR Not a good question tbh as there many formulas for working out voltage using different variables and constants.
They will have different variables, in different configurations.
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
3 variables
