\n" ); document.write( "A= L*W
\n" ); document.write( "L= 5x+4
\n" ); document.write( "W= x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solution:
\n" ); document.write( "96 = (5x+4) * (x) : Distribute
\n" ); document.write( " $\"96+=+5x%5E2+%2B+4x\"$
\n" ); document.write( " $\"+5x%5E2+%2B+4x+-+96+\"$ : Factor out
\n" ); document.write( "(5x +24) (x-4) : Eliminate (5x+24) since it is negative
\n" ); document.write( "Hence, we will use (x-4) which is x=4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute x to get the answers:
\n" ); document.write( "L= 5x+4
\n" ); document.write( "L= 5(4) +4
\n" ); document.write( "L= 20+4
\n" ); document.write( "L= 24ft\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "W= x
\n" ); document.write( "W= 4ft \n" ); document.write( "
