This is a word problem and I can't use the perfect square I have to use the quadratic equation
\n" ); document.write( "5x7 photo that I have to put on a piece of paper
\n" ); document.write( "the area of the mat should equal that of the picture. I have to determine the proper l and width.
\n" ); document.write( "5x7 = 35 sp\"
\n" ); document.write( "(5 + 2x)(7+2x) = 35
\n" ); document.write( "Actually, the total area of the paper has to be 70 sq inches, since 35 will be covered by the photo.
\n" ); document.write( "(2x+5)*(2x+7) = 70
\n" ); document.write( "4x^2 + 24x - 35 = 0
\n" ); document.write( "x = 1.213 inches \n" ); document.write( "
\n" );
