Solution:
<u>Note that:</u>
- 1 min = 60 sec
- 1 h = 60 min.
<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>
- => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes
<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>
- => 420 minutes = 420 ÷ 60 hours = 7 hours
<u>We can conclude that:</u>
- 25,200 seconds = 420 minutes = 7 hours

Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
