x=7 because if you replace x with 7 then 4 times 7 is 28 and 28 minus 6 is 22
Given:
The diameter of cloud-water droplet is

The diameter of pinhead is 0.001.
Explanation:
Divide the dimater of cloud-water droplet by dimater of pinhead to determine the times as great is the diameter of a pinhead as the diameter of a cloud-water droplet .

So diameter of a pin-head is 100 times the diameter of water-droplet.
Ellipse is your answer, because if you plug the equation into a graphing calculator and identify the conic, the term ellipse is given-
You have 6 variables with 2 levels each. Thus 2*2*2*2*2*2 or 2^6 or 64.
