Algebra.Com's Answer #354304 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the formula for the length of a right triangle is a^2 + b^2 = c^2 \n" ); document.write( "a and b are legs of the triangle. \n" ); document.write( "c is the hypotenuse of the triangle. \n" ); document.write( "you are given: \n" ); document.write( "a = x \n" ); document.write( "b = x+1 \n" ); document.write( "c = x+3 \n" ); document.write( "you need to solve for x. \n" ); document.write( "the attached file shows the progression. \n" ); document.write( " ![]() \n" ); document.write( "number 1 shows the formula used. \n" ); document.write( "number 2 simplifies the equation by multiplying the factors shown. \n" ); document.write( "number 3 simplifies further by combining like terms. \n" ); document.write( "number 4 moves everything from the right hand side of the eqution to the left hand side of the equation. \n" ); document.write( "number 5 combines like terms. \n" ); document.write( "number 6 places 8 to the right hand side of the equation to prepare for solving by completing the squares method. \n" ); document.write( "number 7 reformats the equation into completing the square form. \n" ); document.write( "number 8 combines like terms. \n" ); document.write( "number 9 takes the square root of both sides of the equation. \n" ); document.write( "number 10 shows you the results of the operation. \n" ); document.write( "i tested the results by subsituting for x in the original equation and it checks out so i'm reasonably sure this is the right answer. \n" ); document.write( "you may want to simplify square root of 12 by showing it as 2 times the square root of 3 (see number 11 in the attached file). \n" ); document.write( "instructions for completing the square method can be found at this website. \n" ); document.write( "http://webgraphing.com/quadraticequation_completingthesquare.jsp \n" ); document.write( "you select solving by completing the squares method and enter the equation of x^2 - 4x - 8 = 0 into the box provide and click on solve it and your answer plus step by step instructions shows up. \n" ); document.write( "if you would rather read how to do it, then go to the following link. \n" ); document.write( "http://www.purplemath.com/modules/solvquad3.htm for instructions. \n" ); document.write( " \n" ); document.write( " |
