Final answer:
The length of segment AB is represented by the equation 11x - 1, but without additional information to solve for x, we cannot provide the numerical value for AB.
Step-by-step explanation:
To find the length of segment AB, we use the given information that point M is between A and B, with lengths AM and MB given by the expressions 5x + 3 and 6x - 4 respectively. Since M is between A and B, the sum of AM and MB will equal AB. Therefore, we can set up the equation 5x + 3 + 6x - 4 = AB.
Simplifying this equation gives us 11x - 1 = AB. To find the value of x, and subsequently AB, we need additional information that equates this expression to a numerical value, which might have been provided but isn't included in the information given in the question.
Unfortunately, without this additional information, we cannot provide the numerical value for the length of AB, only its expression in terms of x.
