The given polynomial is:

The first step to factor taking out the GCF is to write each term in prime factored form, so:

The second step is to identify the factors common in all terms, they are: 3xcxd
Finally, factor out the GCF:

The answer is above
Answer:
r = 31.85 in or 100/π
Step-by-step explanation:
area = πd
200 = 3.14d
d = 63.69
r = 1/2d
r = 31.85 in
Polygon area = n*side length^2 / [4*tan(180/n)]
side length^2 = polygon area * [4*tan(180/n)] / n
where n is the number of sides
side length^2 = 55 sq inches * (4*tan(180/6)) / 6
side length^2 = 55 sq inches * 4 * tan (30) / 6
side length^2 = (55 sq inches * 4 * 0.57735) / 6
side length^2 =

/ 6
side length^2 =

84/4= 21 students/ teacher
21*25= 525 students/ 25 teachers
You can multiply 3/5 by $220 and that should give you the answer 132.
