1 is A.  You need to distribute the external values to everything in the parentheses.
1.   3(21 + 27) 
     3 x 21 = 63   3 x 27 = 81
so..............
it together is
63 + 81 is the answer

2. 7 x (-3) 
parenthesis means its not negative unless the negative symbol isnt on the outside
so the answer is
21
