document.write( "Question 946208: I don't even know where to begin with this problem. A page of a magazine contains 36 square inches of type. The height of the page is twice the width. If the margin around the type is 3 inches uniformly, what are the dimensions of the page? I know I have to set up a quadratic equation but I don't know what to put where. \n" ); document.write( "

You can put this solution on YOUR website!
First off name the variables.
\n" ); document.write( "\"H\" - length of the page
\n" ); document.write( "\"W\" - width of the page
\n" ); document.write( "Write down what you know in algebraic language.
\n" ); document.write( "1.\"H=2W\"
\n" ); document.write( "The type doesn't take up the whole page because of the margin.
\n" ); document.write( "Remember margin on top and bottom, margin on right and left.
\n" ); document.write( "So the printed area is,
\n" ); document.write( "2.\"%28H-6%29%28W-6%29=36\"
\n" ); document.write( "Substitute from eq. 1 into eq. 2,
\n" ); document.write( "\"%282W-6%29%28W-6%29=36\"
\n" ); document.write( "Looks like the quadratic equation you need.
\n" ); document.write( "Now solve.
\n" ); document.write( "\"2W%5E2-12W-6W%2B36=36\"
\n" ); document.write( "\"2W%5E2-18W=0\"
\n" ); document.write( "Solve for \"W\" then go back and solve for \"H\".
\n" ); document.write( "Repost if you get stuck.
\n" ); document.write( "Hint : Factor out W and solve.\r
