Question 169153
Can you tell me what the perimeter of a rectangular backyard is that is 
6x + 6 yards.  If the width is x yards, can you please find a bionomial that
represents the length.  Thanks!


The perimeter is 2 times the width plus 2 times the length.  If the width is x and the perimeter is 6x+6, than the expression that equals the length would be:


{{{length=((6x+6)-2x)/2}}}


The expression above is derived from the following:
{{{2(width)+2(length)=perimeter}}}
{{{2x+2(length)=6x+6}}}
{{{2(length)=6x+6-2x}}}
{{{length=((6x+6)-2x)/2}}}


Now simplify the expression {{{length=((6x+6)-2x)/2}}}:


{{{length=(4x+6)/2}}}
{{{length=2x+3}}}
