This regular polygon, having eight sides and 45º angle in similar parts, when rotating 360º, will find a similar image and a similar angle of 45º, therefore dividing the angle of 360º by 45º will be the Number of coincidences<span> in image.
</span><span>Solving, thus, we have:

roots of a polynomial are (x-c1)(x-c2)(x-c3) .......(x-cn). Basically, plug every root you have into a (x-__) and then multiply them all together. Just be careful of signs. If your root is positive, it is written as (x-__). If your root is negative, it is written (x+__)

Answer:
51,000
Step-by-step explanation:
50,000
20% raise is
50,000 + 50,000 * 20/100
= 50,000 + 10,000
= 60,000
15% tax is
60,000 * 15/100
= 9000
so total money is 60000 - 9000
= 51000
