The ratio of the coefficients of x(4) to that of the term independent of x in the expansion of (x^(2)+(9)/(x^(2)))^(18) is ____________

x gt0 {:("Quantity A","Quantity B"),((4x^(2)+2x^(2)+3x+9)/(2x),2x+x+(3)/(2)+(18)/(4x)):}

The lengths of the sides of an isosceles triangle are 9+x^(2),9+x^(2) and 18-2x^(2) units Calcule are 9+x^(2),9+x^(2) and 18-2x^(2) units. and find the value of x which makes the area maximum.
