Answer:

Step-by-step explanation:
Let the number be x;
The product of 4 and the number will be;

The the square of the number is given as;

Taking the difference of both expressions above;

Factor out the common term:

Hence the difference between the product of 4 and a  number and the square of the number is 
 
        
             
        
        
        
Answer:
0.44
Step-by-step explanation:
2/3 - 2/9 = 0.44
 
        
                    
             
        
        
        
350 more compact car spaces are available 
2/5 = 0.4 = 40%
40% of 1,000 is 400
400 spots are for compact cars
On Tuesday tner were 150
So there is 350. more spots available
400-150 = 350
        
             
        
        
        
One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3
Solution step by step
1) Sum -4/5 to both sides
4y - 2/5y + 4/5 - 4/5 = -3 -4/5
2) Sum alike terms
18/5 y = -19/5
3) Multiply both sides by 5
18 y = -19
4) Divide both sides by 18
y = -19/18
