Answer:
75
Step-by-step explanation:
Number of necklace= k × amount of time spent
6= k × 2/5
K = 6÷2/5
K= 6×5/2
K= 15
Therefore the number of necklace made in 5 hours can be calculated as follows
15 = number of necklace ÷ 5
Number of necklace = 15 ×5
Number of necklace = 75

<u>Answer</u>
9+√14
<u>Explanation</u>
To Rationalize the denominator of 5-√7/9-√14.
To rationalize this we multiply both the denominator and denominator by the conjugate of the denominator.
The denominator is 9-√14 and its conjugate is (9+√14).
(5-√7)/(9-√14) = (5-√7)(9+√14)/(9-√14)(9+√14)
= (5-√7)(9+√14)/(9²-14)
= (45 + 5√14 - 9√7 - √98)/(81-14)
= (45 + 5√14 - 9√7 - √98)/67
= (45 + 5√14 - 9√7 - 7√2)67
This is the rationalized expression.
The denominator is (9-√14) and its conjugate is (9+√14).
