Algebra.Com's Answer #181402 by dabanfield(803)![]() ![]() ![]() You can put this solution on YOUR website! A print is 10 cm longer than it is wide. It is mounted in a frame 1.5cm wide. The area of the frame is 399cm^2. Find the dimensions of the print\r \n" ); document.write( "\n" ); document.write( "Let x be the width of the print. \n" ); document.write( "The length then is x+10.\r \n" ); document.write( "\n" ); document.write( "The width of the frame is x+1.5 and the length is (x+10)+1.5 = x+11.5\r \n" ); document.write( "\n" ); document.write( "Since the area of the frame is length times width we have:\r \n" ); document.write( "\n" ); document.write( "(x+1.5)*(x+11.5) = 399\r \n" ); document.write( "\n" ); document.write( "Solve this equation for x (width) and then calculate the length x+10. \n" ); document.write( " |
