Answer:
Divisible by 3 is the answer
Step-by-step explanation:
First get everything to have the same base of 5
25^11 - 5^19
(5^2)^11 - 5^19
5^(2*11) - 5^19
5^22 - 5^19
Now factor out the GCF 5^19 to get
5^22 - 5^19
5^(19+3) - 5^(19+0)
5^19*5^3 - 5^19*5^0
5^19(5^3 - 5^0)
5^19(125 - 1)
5^19*(124)
At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4
Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4
Since 31 is a factor of the original expression, this means the original expression is divisible by 31.

Answer:
16m
8m
50.24m
200.96m^2
Step-by-step explanation:
13. 8*2=16
14. 8m
15. 2pi r = 2* pi* 8= 50.24
16. pi r^2 = pi * 8^2= 200.96m^2
Answer:
8 am Monday
Step-by-step explanation:
The difference between the two watches is 2+1= 3 minutes.
It would take 60/3 = 20 hours to have a difference of 60 minutes.
From noon Sunday it would be more 20 hours the earliest time there would be a difference of one hour between the two watches' time.
12 noon + 20 hours= 8 am Monday
