Algebra.Com's Answer #96090 by 067isa(13)![]() ![]() ![]() You can put this solution on YOUR website! The length of a rectangular flower bed is 3 feet less than twice its width. The area of the bed is 54 sq. ft. Find the dimensions of the flower bed. \r \n" ); document.write( "\n" ); document.write( "ask your self what is the shape? rectangualr \n" ); document.write( " then ask what is the Area the rectangular= length * width = L.W \n" ); document.write( "then what is the perimeter = 2 L + 2 w\r \n" ); document.write( "\n" ); document.write( "L = 3-2W \" Length is 3 less than twice the width \" i translate it into math \n" ); document.write( "A= 54------> L.W=54 solve for L------> L= 54/w\r \n" ); document.write( "\n" ); document.write( "sub this value in the first equation instead of L\r \n" ); document.write( "\n" ); document.write( "L= 3-2w \n" ); document.write( "54/w = 3-2w multiply by W to get ridoff the fraction \n" ); document.write( "54=3w-2w^2 \n" ); document.write( "collect then in one side \n" ); document.write( "2w^2-3W+54=0 \n" ); document.write( " factor this \n" ); document.write( " \n" ); document.write( "x= -(-3)+-sqrt((-3)^2-4(2)(54)) /2*(2) = 3+- sqrt(negative #) \n" ); document.write( "CAN NOT BE FACTORED \n" ); document.write( " |
