Answer:
x = 15 
Therefore, the length and width are 31 and 47. 
Step-by-step explanation:
Perimeter = (2x + 1) + (2x + 1) + (3x + 2) + (3x + 2) = 156
Simplified, 
10x + 6 = 156
Subtract 6 from both sides, then divide by 10. 
10x = 150 
x = 15 
To find the length and width, substitute 15 (the value of x) into the individual equations. 
2(15) + 1 = 31
3(15) + 2 = 47
 
        
             
        
        
        
The answer is 4 if I am correct
        
                    
             
        
        
        
Answer:
All expressions are correct
Step-by-step explanation:
9z+7z = 16 z
We need to find an expression ( or expressions ) that are equal to 16z
6z+3z+ 7z = 16z  Correct
z+8z+7z = 16z   Correct
z*16 = 16z  Correct
21z+ -5z = 16z  Correct
 
        
             
        
        
        
Then c = 22 just keep adding 7 
8+7=15 15+7=22
