Answer:
  w = 2, EF = 30 , FG = 42
Explanation:
 We have EF = 5w + 20  and FG = 7w + 28
  Since these points E, F and G are col-linear points we have.
     EG = EF + FG
   And given that EG = 72
 So, EF+EG = 72
      5w + 20 + 7w + 28 = 72
      12w + 48 = 72
       12 w = 24
        w = 2
 So EF = 5w + 20 = 5x2 + 20 = 30
      FG = 7w + 28 = 7x2 + 28 = 42
 
        
             
        
        
        
A is correct.
-8, -4, 0, 2
-|-4| becomes -(4) which becomes -4.
        
                    
             
        
        
        
Answer:
3 or (0,3)
Step-by-step explanation:
 
        
             
        
        
        
<span>Let the major axis = 2a , and the minor axis = 2b
∴ a = 26/2 = 13    and   b = 24/2 = 12
and the equation of foci:
c² = a² - b²
    = 13² - 12² = 169 - 144 = 25
∴ c = √25 = 5
∴ The distance between the foci = 2 * 5 = 10
