<span>The inequality |2x − 6| less than or equal to 10 can be expressed as two form like this to get two value of x
2x-6 </span>≤<span> 10
2x</span>≤10+6
x≤8<span>
-(</span>2x-6) ≤ 10<span>
2x-6 </span>≥<span> -10
2x</span>≥-10+6
x≥-4
<span>
The graph of the inequality would be: </span> 
x≤8 and x≥-4   
or    
-4≤x≤8 
        
             
        
        
        
The surface area (SA) of a cube can be written as:
SA = 6s²
From here we can write, the length of the side s as:

For cube with surface area of 1200 square inches, the side length will be:

 inches
For cube with surface area 768 square inches, the side length will be:

 inches
The difference in side lengths of two cubes will be:
Rounding to nearest tenth of an integer, the difference between the side lengths of two cubes will be 2.8 inches.
