Write a polynomial to represent the volume of the rectangular prism.
\n" ); document.write( "Length= x+5
\n" ); document.write( "Width= x-4
\n" ); document.write( "Height= 1/2x-3
\n" ); document.write( "So far I've got:
\n" ); document.write( "v=(x+5)(x-4)(1/2x-3)
\n" ); document.write( "-----
\n" ); document.write( "V = (x^2+x-20)((1/2)x - 3)
\n" ); document.write( "-----
\n" ); document.write( "V = (1/2)x(x^2+x-20) -3(x^2+x-20)
\n" ); document.write( "------
\n" ); document.write( "V = (1/2)x^3 + (1/2)x^2 - 10x - 3x^2 -x + 20
\n" ); document.write( "----
\n" ); document.write( "V = (1/2)x^3 - (5/2)x^2 - 11x + 20
