Answer: D) 2x+19

Step-by-step explanation:

Given : During a walkathon,

Total distance traveled by Team A = 6x+12 miles and

Total distance traveled by Team B = 4x-7 miles.

Now, the difference in miles between the two teams = Total distance traveled by Team A - Total distance traveled by Team B

[tex]=6x+12-(4x-7)\\\\=6x+12-4x+7[/tex]  [∵ (-)(-)=(+)]

[tex]=6x-4x+12+7\\\\= 2x+19[/tex]

Hence, the  difference in miles between the two teams = 2x+19

Thus , the correct answer is D) 2x+19 .

Answer6-4 = 2x, 12+7=19 so it will be 2x+19
