To solve the compound inequality and , start by simplifying both sides of each inequality. For the first inequality, expanding the left side gives . Subtracting yields , which simplifies to . For the second inequality, expanding gives . Adding results in , which simplifies to . Graphing each solution shows that the values satisfying both conditions must be in the overlap. The graph of is shaded to the left with a right bracket at , and is shaded to the left with a right parenthesis at . The intersection of these two graphs is simply the region where , because any number less than or equal to is also automatically less than . In interval notation, this final combined solution is written as .

A quality control technician is ensuring that a batch of medicine is stored within two safety temperature constraints. To find the final safe storage range, they must determine the values that satisfy both inequalities simultaneously (using 'and'). Arrange the following steps in the correct order to solve this problem.
A logistics manager at a distribution center is verifying that a shipping container's weight satisfies two separate safety constraints simultaneously (using 'and'). To find the final range of acceptable weights, they follow a standard three-step mathematical procedure. Match each step of this procedure with its corresponding action.
A quality control specialist is verifying that a precision-engineered bolt's diameter satisfies two different tolerance limits at the same time (joined by the word 'and'). According to the standard three-step mathematical procedure, after solving each individual inequality in Step 1, what is the specific objective of Step 2?
A quality control inspector is monitoring the thickness of a steel plate, which must satisfy two separate tolerance limits joined by the word 'and'. After independently solving each inequality and graphing the region where they overlap, the inspector follows the final step of the standard procedure by recording the solution set in standard ________ notation.
