The length of a rectangle is twice its width. If the perimeter of the rectangle is 60 ft, find its area\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. The perimeter P means adding up all the four sides of a rectangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let w be the width.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Let 2w be the length\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Then, P=w+w+2w+2w=60.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. Solving yields the following steps\r

DETAILED EXPLANATION

\n" ); document.write( "
Look at .
Eliminated similar terms \"highlight_red%28+w+%29\",\"highlight_red%28+w+%29\",\"highlight_red%28+2%2Aw+%29\",\"highlight_red%28+2%2Aw+%29\" replacing them with \"highlight_green%28+%281%2B1%2B2%2B2%29%2Aw+%29\"
It becomes \"highlight_green%28+%281%2B1%2B2%2B2%29%2Aw+%29=60\".
\n" ); document.write( "
Look at .
Added fractions or integers together
It becomes \"%28highlight_green%28+6+%29%29%2Aw=60\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+6+%29%29%2Aw+%29=60\".
Remove unneeded parentheses around factor \"highlight_red%28+6+%29\"
It becomes \"highlight_green%28+6+%29%2Aw=60\".
\n" ); document.write( "
Look at \"6%2Aw=highlight_red%28+60+%29\".
Moved these terms to the left \"highlight_green%28+-60+%29\"
It becomes \"6%2Aw-highlight_green%28+60+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+6%2Aw-60+%29=0\".
Solved linear equation \"highlight_red%28+6%2Aw-60=0+%29\" equivalent to 6*w-60 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
