The average of a non-zero number and its square is 5 times the number. The number is:

• Number= 9
  Given (x+x^2)/2=5x or x^2=9x So x=9
• 11 years agoHelpfull: Yes(11) No(2)
• 9
  (x+x^2)/2=5x
  x^2=9x
  x=9
• 11 years agoHelpfull: Yes(7) No(2)
• Let no be x
  Acc to que, (x+x^2)/2=5x
  x^2=9x
  x(x-9)=0 => x=0,9
  But no is non zero, so answer is 9

• Let the number be X.
  Then
  
  (X+X^2) / 2= 5X
  
  X+X^2=10X
  
  X^2 - 9X=0
  X(X-9)=0
  
  X=0,9
  
  But the number is non Zero, So, X=9

• 9.0
  (9+(9^2)/2=(9+81)/2=45 = 5* NUMBER(9)

• 3-1^3+6
  =3-1+6
  =2+6
  =8
• 10 years agoHelpfull: Yes(2) No(4)
• (X+X^2)/2=5X
  So on solving we get X=9.

• Let no be x
  Acc to que, (x+x^2)/2=5x
  x^2=10x

• Let the number be x.then,
  (x+x^2)/2=5(x) -----------1
  from 1,
  10x-x=x^2
  x^2-9x=0====>x(x-9)=0
  ==>x=0 or x=9,sub x=9 in 1 and check out.
  Hence the answer is 9

• X^2=5*X
  5^2=5*5=25
• 9 years agoHelpfull: Yes(0) No(0)
• (9+81)/2=45 ------->5*9
  
• 8 years agoHelpfull: Yes(0) No(0)
• Number= 9
  Given (x+x^2)/2=5x or x^2=9x
  So x=9
