Answer:

#2(x+8)#

Explanation:

The word "SUM" means ADD and should always be used with the word "AND" to indicate which numbers are being added,.

In this case, I suspect the expression could be written as.
"Twice the sum of 8 and a number"

The sum of 8 and a number is written as #8 + x #

"Twice" means "double" or multiply by 2.

#2(x+8)#
