Best ResponseYou've already chosen the best response.2Simply do algebraic multiplication of the terms inside the parenthesis. So your steps would be 1) 5x  2(7x+1) 2) 5x [ (2*7x) + (2*1)] 3) 5x  [14x + 2] (the subtraction sign before the squared bracket means everything inside the bracket will be multiplied by '1] 4) 5x  14x 2 5) 9x 2 Hence the answer for this is 'A'
