so the lengths of the sides are 5, 18, 16
 
                                
             
                    
              
              
                
                
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

Answer: 11/6 or 1 5/6
<u>Simplify 6/3</u>
6/3÷3/3=2/1
<u>Change 2/1</u>
2/1×6/6=12/6
New Problem: 12/6+(-1/6)
<u>Add</u>
12+-1/6=11/6
<u>Simplify</u>
11/6 = 1 5/6
