Answer:
B. 18
Step-by-step explanation:
Given:
There are two chord in the circle.
These chords are divided in two segments.
Segments of 1 chord is 21 and 6.
Segments of 2 chord is x and 7.
Now by using Intersecting Chord Theorem which states,
"When two chords intersect each other inside a circle, the products of their segments are equal."
Hence from above theorem we can say that;

Hence the Value of x is 18.
4y.
Is the answer
Hope this helps
Given:
The sequence formula;
Tn = 4.5n - 8 (Where n = term number)
Required:
15th term = ?
Procedure:
All you need to do is use n = 15
T15 = 4.5(15) - 8
T15 = 59.5
Conclusion:
The 15th term of the sequence is 59.5.
Step-by-step explanation:
= (15 − 3) ÷ (2 + 1) × (8 − 6)
BODMAS rule
= (12) ÷ (3) × (2)
= (12/3) × (2)
= 4 × 2
= 8
Hope this helps you. Do mark me as brainliest.
It's 5 because the fraction when you divide. 23.
