Question 23050
{{{6x+x+x+1/4x(x)=450}}}
{{{8x+1/4x^2-450=0}}} remove 4
{{{x^2+32x-1800=0}}}
Use Qudratic formula: {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
a= 1, b=32, c=-1800
{{{x = (-32 +- sqrt( 32^2-4(1)(-1800) ))/2(1)) }}}
simplify: Add: {{{ x = (2)sqrt(514+8))}}}
x = 62 (rounded)
62 x 6 =372

62/4 =15.5 ---> 16



Hence, the lion weights 62pounds, the giaff weights 372 pounds are the lion weights 16 pounds.
16+372+62=450
