Did you make up the problem yourself? Seems pretty cool!

Never learned pascals triangle. So I'm not sure what the question means.

By subsituting real numbers (specifically integers)

If n = 2

x^2 + 2x + 1 and n choose k will be 2

then the variable will be x

If n = 3

(x + 1)(x^2 +2x + 1)

x^3 + 2x^2 + x + x^2 + 2x + 1

x^3 + 3x^2 + 3x + 1

n choose k will be 3

then the variable will be x

So far I think the answer is x

An alternate method, I always like those!

Prime Factoring:

2 * 1200

2 * 2 * 600

2 * 2 * 2 * 300

2 * 2 * 2 * 2 * 150

2 * 2 * 2 * 2 * 2 * 75

2 * 2 * 2 * 2 * 2 * 5 * 15

2 * 2 * 2 * 2 * 2 * 5 * 5 * 3

Set up:

- By the two tangent theorem, we can find the length of the sides of the trapezoid.

- I calculated the shorter leg of the right triangle with hypotenuse AD by doing (DC - AB) / 2

- The height of the longer leg of the right triangles is equal to the diameter indicated by the red line.

Calculate:

By pythagorean theorem

(x + y)² - (x - y)² =

x² + 2xy + y² - (x² -2xy + y²) = 

4xy

Diameter = sqrt(4xy)

Diameter = \(2\sqrt{xy}\)

Radius = \(\sqrt{xy}\)

Working on it right now.

It is the most understandable method

Find the side lengths

\(\sqrt{16}\) = 4

\(\sqrt{49}\) = 7

Now find the scale factor!
