Algebra.Com's Answer #795290 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The other tutor didn't read the problem correctly.... \n" ); document.write( "The area is length times width; and the length is 6 (feet) longer than the width. \n" ); document.write( "x = width \n" ); document.write( "x+6 = length \n" ); document.write( "The area is 72: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "To solve that, you need to factor the quadratic by finding two numbers whose product is 72 and whose difference is 6. \n" ); document.write( "But that is what the original problem requires you to do. \n" ); document.write( "So the formal algebra doesn't help you solve the problem; so (if a formal algebraic solution is not required) solve it mentally by finding two numbers that differ by 6 and have a product of 72: 6 and 12. \n" ); document.write( "ANSWER: the garden is 6 by 12 feet. \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
