fin the lenght, width, and height this is the information they gave me.
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"the area of the base of the box is 20 square inches\"
\n" ); document.write( "L * W = 20
\n" ); document.write( ":
\n" ); document.write( "\"the perimeter of the base of the box is 18 inches\"
\n" ); document.write( "2L + 2W = 18
\n" ); document.write( "simplify, divide by 2
\n" ); document.write( "L + W = 9
\n" ); document.write( "L = (9-W)
\n" ); document.write( ":
\n" ); document.write( "Replace L with (9-W) in the area equation
\n" ); document.write( "W(9-W) = 20
\n" ); document.write( "-W^2 + 9W = 20
\n" ); document.write( "0 = W^2 - 9W + 20; a quadratic equation, that will easily factor to:
\n" ); document.write( "(W-4)(W-5) = 0
\n" ); document.write( "two solutions
\n" ); document.write( "W = 4, then L = 5
\n" ); document.write( "W = 5, then L = 4
\n" ); document.write( ":
\n" ); document.write( "\"the volume of the box is 160 cubic inches\"
\n" ); document.write( "Find the height by dividing the volume by the area of the base (20)
\n" ); document.write( "\"160%2F20\" = 8 inches is the height
\n" ); document.write( ";
\n" ); document.write( ";
\n" ); document.write( "The dimensions of the box 5 by 4 by 8
\n" ); document.write( "
\n" );
