the real solutions for the equation  are -
 are -

Step-by-step explanation:
     =
 = 
     = 0
  = 0 
    We can write 64 as   
 
    +
 +  = 0
 = 0
   using the identity  (  )
 ) 
 we get,
   = 
   =  ....................(1)
    ....................(1)
  solving the quadratic equation  ,
     =0
 =0
solutions of this quadratic equation can be obtained by 
    
 let use y for factors




<u /> ..................(2)
    ..................(2)
from the equation 1 we have,

which gives solution  
 
 and from equation 2 we got  
so the real solutions for the equation  are -
 are - 

 
        
             
        
        
        
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor 
Because both 100 and 140 share a common factor of 20 
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio

Hello!
The angles are supplementary meaning they add to 180°
a + 2a + 3 = 180
Combine like terms
3a + 3 =  180
Subtract 3 from both sides
3a = 177
Divide both sides by 3
a = 59
the answer is 59°
Hope this helps!
