It can represent formulas like A=L×W etc...
What are all the formulas in math? There are hundreds, too many to name here in all the categories of mathematics. Most of them are in geometry, for coordinate geometry, area, and volume.
variables are all related because they can equal to any number
To understand the formulas and concepts in algebra very easily and also in order to solve the problem much efficiently
You can find many formulas in which time is one of the variables. For example, the distance formula states that distance is equal to speed multiplied by the time. You can find time by saying that it is equal to distance divided by speed.
There is no limit to the number of variables a formula can have.

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.
All variables except one, the experimental variable, are kept constant in an experiment.
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
4, the answer is 4.
