Answer: 104 (Good chance its wrong)
Step-by-step explanation: if the ratio is 3:1 then there's 3 times as much boys as girls. if there are 52 more boys then that means 52 is twice as much as the number of girls so if we divide is by 2 we get 26. if we add 26 with 52 we get 78 and if we divide 78 by 3 we get 26. so I believe there are 26 girls and 78 boys. 26+78=104
I believe 104 is the answer but there's a good chance i'm wrong.
 
        
             
        
        
        
Answer:
   yes
Step-by-step explanation:
If all contributors to the distribution are doubled, the value of any particular item in the distribution will be double what it was. That is, it will be different.
 
        
             
        
        
        
This is a quadratic equation, i.e. an equation involving a polynomial of degree 2. To solve them, you must rearrange them first, so that all terms are on the same side, so we get

i.e. now we're looking for the roots of the polynomial. To find them, we can use the following formula:

where  is a compact way to indicate both solutions

 and  , while
, while  are the coefficients of the quadratic equation, i.e. we consider the polynomial

.
So, in your case, we have 
Plug those values into the formula to get

So, the two solutions are
