Answer:
(7x^2 -1)(x - 2).
Step-by-step explanation:
7x^3 - 14x^2 - x + 2
We can factor this by grouping - that is factoring the first 2 terms and the last 2:
= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:
(7x^2 -1)(x - 2).

The circumference of the smaller circle is
.
The given parameters:
- Radius of the larger circle = x
- Radius of the smaller circle = ¹/₃ x
The circumference of the smaller circle is calculated as follows;
![C = 2\pi r\\\\C = 2\pi (\frac{x}{3} )\\\\C = [\frac{2\pi}{3} ]x \ units](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r%5C%5C%5C%5CC%20%3D%202%5Cpi%20%28%5Cfrac%7Bx%7D%7B3%7D%20%29%5C%5C%5C%5CC%20%3D%20%5B%5Cfrac%7B2%5Cpi%7D%7B3%7D%20%5Dx%20%5C%20units)
Thus, the circumference of the smaller circle is

Answer:
6
Step-by-step explanation:
The radius of a circle does not change with direction, it stays constant. This, the radius of the bigger circle is 4, and of the smaller circle is 2. Thus, OP equals 4 + 2 = 6. You're correct! :)
For ADC you just add those two numbers. your answer would be D) 131
