Answer:
The statement b) is individually sufficient to prove than 289 is a factor of n
Step-by-step explanation:
The least common multiple of n and 272 is the smallest number that is a multiple of n and a multiple of 272. Therefore:
272 x X = 4624 ⇒ X = 17 but 272 = 17 · 16 and 289 = 17 · 17
Therefore 17·17 must be a factor of n. That means 289 is a factor of n
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :
Given, the equation of circle
By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)
BC = 10
BC = BD - CD
BC = 14 - 4
