You can put this solution on YOUR website!
P=2[length + width] [Formula for a perimeter]
\n" ); document.write( "(6x+6)=2[(length) + (x)] [Plug-in the given values]
\n" ); document.write( "6x+6=2(length) + 2x [Distribute the 2]
\n" ); document.write( "(6x+6) - 2x = 2(length) +2x-2x [Solve for length]
\n" ); document.write( "6x+6-2x=2(length)
\n" ); document.write( "4x+6=2(length)
\n" ); document.write( "(4x+6)/2=2(length)/2
\n" ); document.write( "(4x+6)/2=length
\n" ); document.write( "2(2x+3)/2 = length [Factor and cancel out]
\n" ); document.write( "2x+3=length [Final answer]
\n" ); document.write( ".
\n" ); document.write( "Check the answer by plugging (length = 2x+3) back into the original formula.
\n" ); document.write( "P=2[length + width] [Returning to the formula for a perimeter]
\n" ); document.write( "P = 2[(x) + (2x+3)]
\n" ); document.write( "P = 2x+4x + 6
\n" ); document.write( "P = 6x+6 [Checks out]
\n" ); document.write( "
\n" );
