Answer:
Douglas is incorrect
Step-by-step explanation:
We can remove a zero from a number that has a zero on the right of the decimal place if that zero is the last number before the decimal place. This is true for 240 divided by 10 because the zeros cancel out:

In 59.20 this is not true. Dividing a number with a decimal place requires the decimal place to move and not cancel out the zero after the decimal place. Therefore:

 
        
             
        
        
        
Answer:

Step-by-step explanation:





 
        
                    
             
        
        
        
First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.

Explanation:</h2>
In this case, we have the following equation:

But we can write this equation as:

So this final result is a quadratic equation written in Standard Form ( ). We need to find the solutions to this equations, so let's use quadratic formula:
). We need to find the solutions to this equations, so let's use quadratic formula:
