Answer 2

We can start by using the ratio given to us to find the lengths of AC and AB.

Let x be a common multiple of 2 and 7, so that we can write:

AC = 2x AB = 7x

We can then use the Pythagorean theorem to find the length of BC:

BC^2 = AC^2 - AB^2 BC^2 = (2x)^2 - (7x)^2 BC^2 = 4x^2 - 49x^2 BC^2 = -45x^2 (Note that this is negative, which means there is no real solution for BC.)

Since there is no real solution for BC, we cannot find its length. However, we can still find the value of AC - AB:

AC - AB = 2x - 7x = -5x

Therefore, AC - AB is equal to -5 times the common multiple we chose earlier, or -5x.

If we are given the value of AC, we can solve for x and then find the values of AB and BC. But with the given information, we can only find AC - AB, which is equal to -5x.
