It has an area of 24.75 ft^2. How long was a side of his old square card table? Use the quadratic equation to solve this word problem. \n" ); document.write( "
Algebra.Com's Answer #593027 by amarjeeth123(569)![]() ![]() ![]() You can put this solution on YOUR website! Let the dimensions of the square card table be x. \n" ); document.write( "Then the length of the rectangular table is (x+2). \n" ); document.write( "Then the width of the rectangular table is (x+1). \n" ); document.write( "We have Area=Length*width \n" ); document.write( "(x+2)(x+1)=24.75 \n" ); document.write( "x^2+3x+2=24.75 \n" ); document.write( "x^2+3x-22.75=0 \n" ); document.write( "x^2+6.5x-3.5x-22.75=0 \n" ); document.write( "x(x+6.5)-3.5(x+6.5)=0 \n" ); document.write( "(x+6.5)(x-3.5)=0 \n" ); document.write( "x=3.5 ft. \n" ); document.write( "The side of the old square table is 3.5 feet. \n" ); document.write( " |
