Algebra.Com's Answer #311643 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! the measure of two sides of a triangle are given. \n" ); document.write( "if p is perimeter, and p=10x+5y, \n" ); document.write( "find the measure of the third side if the other two sides are 3x+4y and 5x-y \n" ); document.write( ": \n" ); document.write( "Let the third side = c \n" ); document.write( "The third side is the other two sides subtracted from the perimeter \n" ); document.write( ": \n" ); document.write( "c = (10x+5y) - (3x+4y) - (5x-y) \n" ); document.write( ": \n" ); document.write( "Remove the brackets, a minus changes the signs so we have: \n" ); document.write( "c = 10x + 5y - 3x - 4y - 5x + y \n" ); document.write( ": \n" ); document.write( "Combine like terms \n" ); document.write( "c = 10x - 3x - 5x + 5y - 4y + y \n" ); document.write( ": \n" ); document.write( "c = 2x + 2y is the 3rd side \n" ); document.write( " \n" ); document.write( " |
