Consider these numbers in turn.
1. 60. This number is composite, because 60=2·2·3·5. Acoording to the rule given in task for this number you can have such possibilities:
- 2 stacks with 30 towels at each;
- 3 stacks with 20 towels at each;
- 4 stacks with 15 towels at each;
- 5 stacks with 12 towels at each;
- 6 stacks with 10 towels at each;
- 10 stacks with 6 towels at each;
- 12 stacks with 5 towels at each;
- 15 stacks with 4 towels at each;
- 20 stacks with 3 towels at each;
- 30 stacks with 2 towels at each.
2. 29 is prime number, because 29=1·29 (has only two trivial divisors). Then you cannot choose numbers of stacks and towels according to the given rule.
3. 37 is prime number, because 37=1·37 (has only two trivial divisors). Then you cannot choose numbers of stacks and towels according to the given rule.
4. 42=2·3·7 is composite number. Acoording to the rule given in task for this number you can have such possibilities:
- 2 stacks with 21 towels at each;
- 3 stacks with 14 towels at each;
- 6 stacks with 7 towels at each;
- 7 stacks with 6 towels at each;
- 14 stacks with 3 towels at each;
- 21 stacks with 2 towels at each.
-2/3*3=-6/3=-2. That is how you do this.
X=8.33
u have to isolate the x on a side ans the numbers on the other side of the equation
F^-1(x) = sqrt 2(-5+x)/2, - sqrt 2(-5+x)/2
