The box below has a volume of 72ft3. Use the equation to solve for x.
\n" ); document.write( " Finally, label the width and the height of the box.
\n" ); document.write( "equations x-3, x+1, and 6 ft.
\n" ); document.write( ":
\n" ); document.write( "The equation will be the volume which is L * W * H, in this problem
\n" ); document.write( "W = (x-3)
\n" ); document.write( "L = (x+1)
\n" ); document.write( "H = 6
\n" ); document.write( ":
\n" ); document.write( "We could write like this
\n" ); document.write( "6*(x-3)*(x+1) = 72
\n" ); document.write( "divide both sides by 6
\n" ); document.write( "(x-3)(x+1) = 72/6
\n" ); document.write( "(x-3)(x+1) = 12
\n" ); document.write( "FOIL
\n" ); document.write( "x^2 + x - 3x - 3 = 12
\n" ); document.write( "Arrange as a quadratic equation
\n" ); document.write( "x^2 - 2x - 3 - 12 = 0
\n" ); document.write( "x^2 - 2x - 15 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(x+3)(x-5) = 0
\n" ); document.write( "Th positive solution is what we want here
\n" ); document.write( "x = 5
\n" ); document.write( "then
\n" ); document.write( "Width: 5-3 = 2 ft
\n" ); document.write( "Length: 5+1 = 6 ft
\n" ); document.write( "Height given as 6 t
\n" ); document.write( ":
\n" ); document.write( "Check the volume 2 * 6 * 6 = 72 cu/ft
\n" ); document.write( " \n" ); document.write( "
