Please answer correctly

x + 3 meters

Step-by-step explanation:

We know that the area of a rectangle is length times width, so if we call the length y, we'll get y * (x - 3) = x² - 9.

y = (x² - 9) / (x - 3)

y = (x + 3)(x - 3) / (x-3)

y = x + 3. Hope this helps!

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
