A student simplified the expression 6 x (9 + 12) as shown. What is her error? May someone please help me, thanks everyone! :)

Thanks!

you mean simplified 6 x 9 + 12 that way? If that is the case, then it should be simplified to 54 + 12 = 66

OpenStudy (anonymous):

Yeah, I did, It's from the book.
