The correct answer is A. -7 - n(10.5 -2.5), because - 3.5 * 2 = -7, -3.5 * 3 = 10.5
So the equation would become -7 - 10.5n -2.5n
Then you combine like terms and the like terms are -10.5n and -2.5, So you would take -10.5n - 2.5n which will come out to be -8
and the answer would -7 - 8n
Hope this helped
