A logistics coordinator is merging two efficiency formulas used to calculate shipping routes: $\frac{2n}{n^2 - 3n - 10}$ and $\frac{6}{n^2 + 5n + 6}$. To combine these expressions, which of the following represents the correct Least Common Denominator (LCD)?

A resource analyst is merging two efficiency formulas: $\frac{2n}{n^2 - 3n - 10}$ and $\frac{6}{n^2 + 5n + 6}$. To correctly combine these metrics, they must identify the specific mathematical components involved in the addition. Match each component to its correct role in the simplification process.

A laboratory technician is calculating the combined flow rate of two separate filtration systems for a chemical processing unit. The rates for the systems are defined by the following rational expressions:

System 1: $\frac{2n}{n^2 - 3n - 10}$

System 2: $\frac{6}{n^2 + 5n + 6}$

Arrange the following mathematical steps in the correct order to find the sum of these two flow rates.

A logistics coordinator is merging two efficiency formulas: $\frac{2n}{n^2 - 3n - 10}$ and $\frac{6}{n^2 + 5n + 6}$. To find a common denominator, the coordinator factors the second denominator, $n^2 + 5n + 6$, as $(n + 3)(n + a)$. Based on the mathematical procedure for this addition, what is the missing integer $a$?

A financial analyst is developing a forecasting tool that combines two cost-efficiency metrics, represented by the rational expressions $\frac{2n}{n^2 - 3n - 10}$ and $\frac{6}{n^2 + 5n + 6}$. In the process of adding these two expressions, the analyst correctly determines that the least common denominator (LCD) is $(n - 5)(n + 2)(n + 3)$.
