Algebra.Com's Answer #45294 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! We are told that the Volume (V) of the box is area x height.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And we are also told that the Volume (V) of the box is (x^2 + 5x + 6)(x + 5) and that the height is x+2 \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now we want to find the polynomial that represents the area of the bottom of the box.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The quadratic (x^2+5x+6) can be readily factored and we get: \n" ); document.write( "(x^2+5x+6)=(x+2)(x+3) but we can see that x+2 is the height of the box so we'll replace it with (h) for height\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "V=area(a) x height (h) = (h)(x+3)(x+5) so we have\r \n" ); document.write( "\n" ); document.write( "a x h =(h)(x+3)(x+5) divide both sides by h and we get: \n" ); document.write( "a=(x+3)(x+5) expanding we have x^2+8x+15\r \n" ); document.write( "\n" ); document.write( "Thus, the area of the bottom of the box is represented by the polynomial:\r \n" ); document.write( "\n" ); document.write( "x^2+8x+15\r \n" ); document.write( "\n" ); document.write( "Hope this helps.
