Question 922820
First find:
{{{ x^2 / y^2 = ( r^2 + 2r*s + s^2 ) / s^2 }}}
{{{ x^2 / y^2 = ( r + s )^2 / s^2 }}}
-----------------
Take the square root of both sides. Since they say
{{{ x>0 }}} and {{{ y>0 }}}, they want positive square roots,
not negative roots
---------------------
{{{ x/y = ( r+s ) / s }}}
or, what is the same:
{{{ x/y = r/s + 1 }}}
