Answer:
Radius: 10.5
Circumeference: 65.97
Area: 346.36
Step-by-step explanation:
Let us assume PQ || BC.
Then, by Basic Proportionality Theorem, we get,
AP/PB = AQ/QC
=> x/(x+7) = (x-3)/(x+1)
=> x (x+1) = (x+7)(x-3)
=> x^2 + x = x^2 - 3x + 7x - 21
=> x = 4x - 21
=> -4x + x = -21
=> -3x = -21
=> 3x = 21
=> x = 21/3
=> x = 7
Therefore, for PQ||BC the value of x should be 7
The answer is 6x³. I will show you step by step how to reach this answer.
3x(2x²) = 6x²x
6x²x = 6x³
It's that simple. Hope I helped you out!
