AD=5X-2

BD=2X+7
FIND AB

To find AB, we need to determine the length of the line segment AB.

First, let's understand the scenario. AB represents a line segment connecting points A and B. We are given the lengths of two smaller line segments, AD and BD. In order to find AB, we need to add the lengths of AD and BD.

Given that:
AD = 5X - 2
BD = 2X + 7

To find AB, we add AD and BD:
AB = AD + BD

Substituting the given values:
AB = (5X - 2) + (2X + 7)

Now, we can simplify the equation by combining like terms:
AB = 5X + 2X - 2 + 7

Continuing to simplify:
AB = 7X + 5

Therefore, the length of the line segment AB is represented by the equation AB = 7X + 5.
