Hello XD
3(x+2) = 3x+6
Distributive property 
(3)(x)+(3)(2) = 3x+6
3x+ 6 = 3x+6
Now subtract 3x from both sides 
3x+6-3x = 3x+6-3x
6=6
Subtract 6 from both sides 
6-6 = 6-6
0=0
In this case the answer is : All real numbers are solution 
 
        
                    
             
        
        
        
Here you go! Hopefully it was correct as i used an app called Cymath.Please mark me as Brainliest!
 
        
        
        
Answer: 43
Step-by-step explanation:
 
        
                    
             
        
        
        
1. Perimeter 
22a + 2(6a + 8) -4 = p
[I got 22a from 12a + 10a]
2. If p = 250, what is a? 
22a + 2(6a + 8) - 4 = 250
Distributive property 
22a + 12a + 16 - 4 = 250
Add like terms 
34a + 12 = 250
Subtract 12 by both sides 
34a = 238
Divide 34 by both sides 
a = 7
