1 is an odd number so let’s put 1 into n, (1)2+4 which equals 2+4 which is 6, 6 is not a prime number as it can has factors such as 2&3 not just 1&6.
Question 1

Answer:
9 Sides
Step-by-step explanation:
According to the Question,
- Given That, The sum of the interior angles(s), in an n-sided polygon can be determined using the formula s=180(n−2), where n is the number of sides
Therefore, The sides do a polygon have if the sum of the interior angles is 1,260°.
Put The Values in Formula, we get
1260=180(n−2)
n-2 = 7
n=9 (9 Sides)
8
Step-by-step explanation:
- Critical Path Analysis is presented using the circle and arrow diagrams.
- Earliest Start Time = the earliest possible time of starting the activity
- An arrow running between two event circles shows the activity needed to complete that task.
- All arrows run left to right
- Time for doing just task E = 8 hours (as shown in the figure)
