X=3 let me know if this is right ;)
        
                    
             
        
        
        
You find this by finding the number of yards in 15 feet (15÷3) and that number of yards in 24 feet (24÷3) and multiplying them together. 5X8=40sq yards.
        
                    
             
        
        
        
Answer should be (A)
This is because the variation factors from one day to another may significantly  influence the distances the football goes. Among these factors are: the weather and Danny's condition. For example: wind strength, wind direction, any rain influences the skid, etc. Condition example could be: Danny is more tired on one of the days and can't kick as strong.
The other choices do not relate to variability.
 
        
             
        
        
        
1. Are you asking how to solve or simplify?
If so, the answer is simple.
PEMDAS 
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
10 divided by 9 times 7 divided by 5.
9 times 7 first. 63 so lets re word the equation
10 divided by 63 divided by 5
now its 6.3 divided by 5
I got 1.26 
 now if i did it the way I was taught in highschool this will be the answer..
1.555555555...
Am I correct with either?
