Algebra.Com's Answer #52974 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! 2(4s - 3t) + 7s + 5t \n" ); document.write( ". \n" ); document.write( "Begin by doing the distributed multiplication of the terms in the parentheses. Multiply \n" ); document.write( "the 2 times the 4s to get 8s and then multiply the 2 times the -3t to get -6t. \n" ); document.write( ". \n" ); document.write( "Put these results into the equation in place of the multiplication to get: \n" ); document.write( ". \n" ); document.write( "8s - 6t + 7s + 5t \n" ); document.write( ". \n" ); document.write( "You can now add the two terms that have an s ... 8s + 7s = 15s \n" ); document.write( ". \n" ); document.write( "And you can also add the two terms that have t in them ... -6t + 5t = -t \n" ); document.write( ". \n" ); document.write( "And therefore you now have the answer of 15s - t \n" ); document.write( ". \n" ); document.write( "This is answer D on your list of possible answers. \n" ); document.write( ". \n" ); document.write( "I hope this helps you to understand how you can solve problems such as these by using a few \n" ); document.write( "rules of basic algebra. \n" ); document.write( " |
