let the 4 sides be a, b, c, d; (a is the longest, d is the shortest)
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "The perimeter of a quadrilateral (four sided polygon) is 29 inches.
\n" ); document.write( "a + b + c + d = 29
\n" ); document.write( ":
\n" ); document.write( " The longest side is twice as long as the shortest side.
\n" ); document.write( "a = 2d
\n" ); document.write( ":
\n" ); document.write( "The other two sides are equally long
\n" ); document.write( "b = c
\n" ); document.write( ":
\n" ); document.write( " and are 2 inches longer than the shortest side.
\n" ); document.write( "b = d + 2
\n" ); document.write( "c = d + 2
\n" ); document.write( ":
\n" ); document.write( "Substitute in the perimeter equation
\n" ); document.write( "a + b + c + d = 29
\n" ); document.write( "2d + (d+2) + (d+2) + d = 29
\n" ); document.write( "5d + 4 = 29
\n" ); document.write( "5d = 29 - 4
\n" ); document.write( "d = \"25%2F5\"
\n" ); document.write( "d = 5
\n" ); document.write( ":
\n" ); document.write( "You should be able to find the other 4 sides now, see that they add up to 29\r
