Answer:
x>-2
Step-by-step explanation:
 13+x>11
Subtract 13 from each side
 13-13+x>11-13
x>-2
 
        
             
        
        
        
Step-by-step explanation:
step 1. This is a right triangle where a^2 + b^2 = c^2 (c is the hypotenuse).
step 2. a^2 + 6^2 = 8^2.
step 3. a^2 = 64 - 36.
step 4. a^2 = 28.
step 5. a (the ladder height along the wall) = sqrt (28) where sqrt is the square root.

Answer:
The inequality that you have is  . You can use mathematical induction as follows:
. You can use mathematical induction as follows:
Step-by-step explanation:
For  we have:
 we have:


Hence, we have that 
Now suppose that the inequality holds for  and let's proof that the same holds for
 and let's proof that the same holds for  . In fact,
. In fact, 

Where the last inequality holds by the induction hypothesis.Then, 




Then, the inequality is True whenever  .
.
 
        
             
        
        
        

In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)
Therefore the answer is 3mn (#3)
