Answer:
10th term of the sequence = 0.537
Step-by-step explanation:
First three terms of the sequence are → 5, 4,
..........
Ratio of 2nd and 1st term of the sequence = 
Ratio of 3rd and 2nd term of the sequence = 
= 
Therefore, ratio between every successive term to the previous term is common.
Common ratio 'r' = 
First term of the sequence 'a' = 5
nth term of a geometric sequence = 
Therefore, nth term of the given term will be 
Now we have to find the 10 term of the given sequence.
For n = 10,

= 0.53687
≈ 0.537
Therefore, 10th term of the sequence is 0.537
2,700 / 12 = 225
225 / 5 = 45
They can make 45 necklaces.
So for this polynomial, we will be completing the square. Firstly, what two terms have a product of 20m^2 and a sum of -12m? That would be -10m and -2m. Replace -12m with -2m - 10m: 
Next, factor m^2 - 2m and -10m + 20 separately. Make sure that they have the same quantity inside of the parentheses: 
Now you can rewrite this expression as
. <u>(m - 10) and (m - 2) are your two factors.</u>
