The area of a rectangular blanket is 33 square feet. The blanket's length is (3x+8) feet and the blankets width is 3x feet. What is the dimension of the blanket? Provide a justification for each step. \r
\n" ); document.write( "\n" ); document.write( "Solve for x
\n" ); document.write( "3x(3x+8)= 33
\n" ); document.write( "Divide by 3
\n" ); document.write( " 3x^2+8x = 11
\n" ); document.write( "3x^2+8x-11 = 0
\n" ); document.write( "(3x+11)(x-1) =
\n" ); document.write( "Get the positive value for x
\n" ); document.write( "x-1 = 0
\n" ); document.write( "x = 1\r
\n" ); document.write( "\n" ); document.write( "Length = (3x+8) = 3+8 = 11
\n" ); document.write( "Width = 3x = 3
