What can be written as compound inequality?

A compound inequality is an expression that combines two inequalities using the Words "and" or "or." For example, the statement "3 < x < 7" can be written as a compound inequality, meaning that x is greater than 3 and less than 7 simultaneously. Another example is "x < -2 or x > 4," indicating that x can be either less than -2 or greater than 4. These inequalities allow for a range of values to be expressed concisely.
