Answer:

#5(x-3)#

Explanation:

The word "SUM" means the answer to an "ADDITION".

"SUM" is always used with the word "AND" to indicate which numbers are being added.

The SUM of a number AND -3 is written as: #(x+(-3)) , or (x-3)#

(where we have chosen the number to be #x#.)

But we want FIVE of those sums; this means:

#5(x-3)#
