A question involving solving linear equations and area. You will have to set up and solve an equation to find `x`.
The topic is Functions, specifically Composite Functions, you will have to substitute a number in to the Composite Function.
This is a ratio problem. You need to be good at finding a missing value when at least one value is given.
Factorising quadratics - remember factorising involves putting the expression into brackets.
This is an inequalties question. Specifically about solving an inequation. It's quite similar to solving 2 equations at the same time. At the end write down the integers (whole numbers) that `x` could be.

The topic is reverse percentages. Don't try and work out 20% or 30% of the figure you've been given as that is not the original amount.
