Question

which expression is equivalent to 6a(5+d)? A. 30a + (6a · d) B. 30a + 6ad C. (6a · 5) + ( 6a · d) D. 30ad E. 11atd

Answer 1

D) 30ad if not correct so sorry. I did it in my head from what I remember.

Answer 2

B

Explanation:

Myself, I'd pick B. It is uncluttered by unnecessary brackets and reduced to its final answer, but that does not mean I am correct. A is correct as well 6ad = 6a*d. C is also correct for the same reason. D is incorrect and incomplete. E is a nightmare.

I'd pick B but don't be surprised if it is A or C.
