Answer:
8 miles away
Step-by-step explanation:
Add the 6 miles and the 2 miles together.
(x+7)(x+3) so therefore you set each equation = 0...
x + 7 = 0
x + 3= 0
and solve
x = -3
x = -7
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
I’m not sure I’ll see if I can get it
