Answer:
x = -1
Step-by-step explanation:
6 − 4x = 6x − 8x + 8
Combine 6x and −8x to get −2x.
6 − 4x = −2x + 8
Add 2x to both sides.
6 − 4x + 2x = 8
Combine −4x and 2x to get −2x.
6 − 2x = 8
Subtract 6 from both sides.
−2x = 8 − 6
Subtract 6 from 8 to get 2.
−2x = 2
Divide both sides by −2.

Divide 2 by −2 to get −1.

Hope this helps and have a great day! =D
 
        
                    
             
        
        
        
Answer:
first put the numbers and unknowns to different sides, as in 6x-3x= 14-5, now solve for x, 3x=9, divide each side by 3 to get the value of x, x=3
Step-by-step explanation:
 
        
                    
             
        
        
        
The answer would be the third one
        
             
        
        
        
If you add them together you will get 11g
        
                    
             
        
        
        
To find the height, you would do the area divided by the base, or in this case,187.5 / 25 which equals 7.5 inches.  Hope this helped!
