Algebra.Com's Answer #266322 by rfadrogane(214) You can put this solution on YOUR website! The area of the rectangle is 84 square inches. Find its length with width \n" ); document.write( "(x+3)bottom of the rectangle (x-2) side of the rectangle. \n" ); document.write( " Sol'n: \n" ); document.write( " A = LW \n" ); document.write( " (x+3)(x-2)= 84 \n" ); document.write( " x^2+x-6 = 84 \n" ); document.write( " x^2+x-90 = 0,factor and equate to zero to find the value of x. \n" ); document.write( " x = 9--acceptable value \n" ); document.write( " x = -10---absurd, since there is no negative value for any magnitude. \n" ); document.write( " for L = x+3 = 12 inches----ans \n" ); document.write( " W = x-2 = 7 inches-----ans \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
