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

Hope this helps,

1 is A. You need to distribute the external values to everything in the parentheses.
