the santa rosa sport complex contain 504 seats.
\n" ); document.write( "there are 3 fewer rows than there are seats per row.
\n" ); document.write( "find the number of rows and seats per row
\n" ); document.write( ":
\n" ); document.write( "let s = the no. of seats per row
\n" ); document.write( "\"there are 3 fewer rows than there are seats per row.\", therefore:
\n" ); document.write( "(s-3) = no. of rows
\n" ); document.write( ":
\n" ); document.write( "s(s-3) = 504
\n" ); document.write( "a quadratic equation
\n" ); document.write( "s^2 - 3s - 504 = 0
\n" ); document.write( "YOu can use the quadratic formula; a=1; b=-3; c=-504, but this will factor to
\n" ); document.write( "(s-24)(s+21) = 0
\n" ); document.write( "the positive solution
\n" ); document.write( "s = 24 seats and obviously 21 rows
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check 24 * 21 = 504 \n" ); document.write( "

\n" );
