As a logistics analyst, you are compiling a consolidated resource report from two different distribution centers. The combined resources are represented by the expression: ${}8a^2 + 12a + 1 + 3a^2 - 5a + 4$. Recalling the procedure for simplifying expressions, which of the following represents the correct consolidated report after combining like terms?

A project supervisor is consolidating material inventory from two warehouse sections. The total inventory is represented by the expression ${}8a^2 + 12a + 1 + 3a^2 - 5a + 4$. To simplify the final report, match each category of like terms with its correct combined total.

A facility manager is consolidating utility and maintenance costs from two buildings. The combined costs are represented by the expression ${}8a^2 + 12a + 1 + 3a^2 - 5a + 4$. Recall the procedure for simplifying algebraic expressions and arrange the following steps in the correct order to reach the final consolidated total.

A logistics manager is consolidating supply chain data represented by the algebraic expression ${}8a^2 + 12a + 1 + 3a^2 - 5a + 4$. To simplify the data for a summary report, the manager combines all like terms. In the final simplified expression, the coefficient of the $a$ term is ____.

A logistics manager is consolidating stock data represented by the expression ${}8a^2 + 12a + 1 + 3a^2 - 5a + 4$. True or False: In the simplified version of this expression, the constant term (the term without a variable) is 5.
