Algebra.Com's Answer #675344 by jorel555(1290)![]() ![]() ![]() You can put this solution on YOUR website! Let t be the thickness of the frame. Then: \n" ); document.write( "(20-2w)(14-2w)=184 \n" ); document.write( "280-68w+4w²=184 \n" ); document.write( "4w²-68w+96=0 \n" ); document.write( "w²-17w+24=0 \n" ); document.write( "Using the quadratic formula, we get two roots of 15.4462219947 and 1.55377800528. The most sensical answer is the smaller root, giving us a frame of width 1.55377800528 inches. ☺☺☺☺ \n" ); document.write( " |
