The length of a rectangle is four more than the width. The perimeter is 40 inches. Find the rectangle's measurements\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 w+4 be the length since the length is 4 more than the width.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Then, P=w+w+w+4+w+4=40.\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 $\"w%2Bw%2Bw%2Bhighlight_red%28+4+%29%2Bw%2Bhighlight_red%28+4+%29=40\"$ .
Added fractions or integers together
It becomes $\"w%2Bw%2Bw%2Bhighlight_green%28+8+%29%2Bw=40\"$ .
\n" ); document.write( "

Look at $\"w%2Bw%2Bw%2Bhighlight_red%28+8+%29%2Bw=40\"$ .
Moved $\"8\"$ to the right of expression
It becomes $\"w%2Bw%2Bw%2Bw%2Bhighlight_green%28+8+%29=40\"$ .
\n" ); document.write( "

Look at

.
Eliminated similar terms $\"highlight_red%28+w+%29\"$ , $\"highlight_red%28+w+%29\"$ , $\"highlight_red%28+w+%29\"$ , $\"highlight_red%28+w+%29\"$ replacing them with $\"highlight_green%28+%281%2B1%2B1%2B1%29%2Aw+%29\"$
It becomes $\"highlight_green%28+%281%2B1%2B1%2B1%29%2Aw+%29%2B8=40\"$ .
\n" ); document.write( "

Look at

.
Added fractions or integers together
It becomes $\"%28highlight_green%28+4+%29%29%2Aw%2B8=40\"$ .
\n" ); document.write( "

Look at $\"highlight_red%28+%28highlight_red%28+4+%29%29%2Aw+%29%2B8=40\"$ .
Remove unneeded parentheses around factor $\"highlight_red%28+4+%29\"$
It becomes $\"highlight_green%28+4+%29%2Aw%2B8=40\"$ .
\n" ); document.write( "

Look at $\"4%2Aw%2B8=highlight_red%28+40+%29\"$ .
Moved these terms to the left $\"highlight_green%28+-40+%29\"$
It becomes $\"4%2Aw%2B8-highlight_green%28+40+%29=0\"$ .
\n" ); document.write( "

Look at $\"4%2Aw%2Bhighlight_red%28+8+%29-highlight_red%28+40+%29=0\"$ .
Added fractions or integers together
It becomes $\"4%2Aw%2Bhighlight_green%28+-32+%29=0\"$ .
\n" ); document.write( "

Look at $\"4%2Aw%2Bhighlight_red%28+-32+%29=0\"$ .
Removed extra sign in front of $\"-32\"$
It becomes $\"4%2Aw-highlight_green%28+32+%29=0\"$ .
\n" ); document.write( "

Look at $\"highlight_red%28+4%2Aw-32+%29=0\"$ .
Solved linear equation $\"highlight_red%28+4%2Aw-32=0+%29\"$ equivalent to 4*w-32 =0
It becomes $\"highlight_green%28+0+%29=0\"$ .
Result: $\"0=0\"$
