Answer:

Difference = 4

Explanation:

Point A has an x-coordinate of -11 and point B has an x-coordinate of -7

So, the difference of their x-coordinates is:


\sf -11 - (-7) = -4

Since it must be positive, so, the difference is 4.

The circles in the question have centers at (-11, 4) and (-7, 4) respectively. The radius of the first circle is 2 and the radius of the second circle is 3.

Since the points A and B are both on the circle with center (-11, 4), they are both 2 units away from the center of the circle.

This means that the x-coordinate of point A is 2 units to the left of the x-coordinate of point B.

Therefore, the difference of the x-coordinate of point A and the x-coordinate of point B is 4.
