Algebra.Com's Answer #54719 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! Use the formula for the perimeter of a rectangle: \n" ); document.write( "P = 2(length+width) \n" ); document.write( "P=32 \n" ); document.write( "Length=width + 7 \n" ); document.write( "Width = w \n" ); document.write( ". \n" ); document.write( "Plug-in the values and solve: \n" ); document.write( "P=2(l+w) \n" ); document.write( "32=2(w+7+w) \n" ); document.write( "32=2(2w+7) \n" ); document.write( "32/2=2(2w+7)/2 \n" ); document.write( "16=2w+7 \n" ); document.write( "16-7=2w \n" ); document.write( "9=2w \n" ); document.write( "9/2=2w/2 \n" ); document.write( "4.5=w \n" ); document.write( ". \n" ); document.write( "Check by plugging all of the values back into the original equation: \n" ); document.write( "32=2(4.5+7+4.5)\r \n" ); document.write( "\n" ); document.write( "32=32 [checks out] \n" ); document.write( " \n" ); document.write( " |
