a rectangular auditorium seats 1050 people.
\n" ); document.write( " the number of seats in each row exceeds the number of rows by 17.
\n" ); document.write( " find the number of seats in each row
\n" ); document.write( ":
\n" ); document.write( "let x = no. rows
\n" ); document.write( " \"the number of seats in each row exceeds the number of rows by 17.\", therefore:
\n" ); document.write( "(x+17) = no. of seats in each row
\n" ); document.write( ":
\n" ); document.write( "Total seats = no. of rows * no. of seats in each row; therefore:
\n" ); document.write( "x(x+17) = 1050
\n" ); document.write( "x^2 + 17x - 1050 = 0
\n" ); document.write( "use the quadratic formula to find x, a=1; b=17; c=-1050
\n" ); document.write( "I got solutions of of
\n" ); document.write( "x = -42
\n" ); document.write( "x = 25
\n" ); document.write( "we want the positive solution here
\n" ); document.write( "x = 25 rows
\n" ); document.write( "then
\n" ); document.write( "25 + 17 = 42 seats in each row
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, find the total with these values
\n" ); document.write( "25 * 42 = 1050
\n" ); document.write( "
\n" );
