Answer:
(-4x-18) miles
Explanation:
Distance walked by team A = (6x + 11) miles
Distance walked by team B = (2x - 7) miles
We need to find the difference in miles between the two teams.
Difference = team B - team A
= (2x - 7)-(6x + 11)
= 2x-6x-7-11
= (-4x-18) miles
So, the difference between the two teams is (-4x-18) miles.
