Algebra.Com's Answer #785677 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "You are calling the second number 27-x, because the sum of x and (27-x) is 27 -- as the problem requires. \n" ); document.write( "So the two numbers are x and (27-x), and their product is 182: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "To solve this using algebra, you need to factor the quadratic expression by finding two numbers whose sum is 27 and whose product is 182. \n" ); document.write( "But that's exactly what the original problem asked you to do. So the formal algebra doesn't help to solve the problem. \n" ); document.write( "To find the answer, find the prime factorization of the product 182 and use it to find a way to write 182 as the product of two numbers whose sum is 27. \n" ); document.write( "182 = 2*91 = 2*7*13 \n" ); document.write( "It should be easy to see that you want to combine the first two factors to get \n" ); document.write( "182 = 14*13 \n" ); document.write( "14+13 = 27, so 14 and 13 are the numbers you are looking for. \n" ); document.write( "ANSWER: 14 and 13 \n" ); document.write( " \n" ); document.write( " |
