Final answer:

To determine the numerical length of AB, substitute the values of AC and BC into the equation AB = AC - BC. Given AC = 2x + 7 and BC = x, substitute these values into the equation and simplify to get AB = x + 7. To find the numerical length of AB, substitute the value of x into the equation.

Step-by-step explanation:

To determine the numerical length of AB, we need to substitute the values of AC and BC into the equation AB = AC - BC. Given AC = 2x + 7 and BC = x, we can substitute these values into the equation: AB = (2x + 7) - x. Simplifying the equation, we get AB = x + 7. To find the numerical length of AB, we need to substitute the value of x into the equation.
