Your company's finance team models quarterly revenue using the expression ${}9b^2 - 5b - 4$ and quarterly expenses using ${}3b^2 - 5b - 7$. To report the projected profit, you must find the difference between revenue and expenses by evaluating $(9b^2 - 5b - 4) - (3b^2 - 5b - 7)$. Arrange the steps in the correct order to simplify this expression.

A logistics coordinator uses the expression ${}9b^2 - 5b - 4$ to represent the operational costs of Route A and ${}3b^2 - 5b - 7$ for Route B. To calculate how much more expensive Route A is than Route B, the coordinator evaluates $({}9b^2 - 5b - 4) - (3b^2 - 5b - 7)$. Based on the simplification steps for this expression, what is the final simplified form?

A project manager at a manufacturing firm is comparing two cost-efficiency models represented by polynomials: Model A is ${}9b^2 - 5b - 4$ and Model B is ${}3b^2 - 5b - 7$. To calculate the difference between the two models, the manager evaluates $({}9b^2 - 5b - 4) - ({}3b^2 - 5b - 7)$. Match each stage of the simplification process with its correct mathematical result.

A project manager is calculating the difference between two quarterly cost-efficiency models represented by the polynomials $(9b^2 - 5b - 4)$ and $(3b^2 - 5b - 7)$. After fully simplifying the difference $(9b^2 - 5b - 4) - (3b^2 - 5b - 7)$, the constant term in the resulting expression is ____.

An operations manager is comparing two production cost models represented by the polynomials $(9b^2 - 5b - 4)$ and $(3b^2 - 5b - 7)$. To calculate the difference between these models, the manager evaluates $(9b^2 - 5b - 4) - (3b^2 - 5b - 7)$. True or False: In the first step of this calculation, distributing the subtraction sign across the second polynomial results in the terms $-3b^2 + 5b + 7$.
