1. simplify the expression 3(21m+27) a) 63m+81 b)63m+27 c)24m+30 d)21m+81 if someone can me with this other one it could too! 2. what is the product? 7 x (-3) a)21 b)-21 c)4 d)10

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

Hope this helps,
