What is the area in square feet of a room that is (2x - 1) feet wide and (7x + 3) feet long?
\n" ); document.write( ".
\n" ); document.write( "Area is:
\n" ); document.write( "length * width
\n" ); document.write( ".
\n" ); document.write( "The problem tells us that:
\n" ); document.write( "width is (2x-1) feet
\n" ); document.write( "length is (7x+3) feet
\n" ); document.write( ".
\n" ); document.write( "Therefore, area must be:
\n" ); document.write( "length * width
\n" ); document.write( "(7x+3)(2x-1)
\n" ); document.write( "Applying \"FOIL\" we get:
\n" ); document.write( "(7x)(2x) + (7x)(-1) + (3)(2x) + (3)(-1)
\n" ); document.write( "= (14x) + (-7x) + (6x) + (-3)
\n" ); document.write( "= 14x + (-7x + 6x) -3
\n" ); document.write( "= 14x + (-x) -3
\n" ); document.write( "= 14x - x -3 square feet\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
