Answer:

Step-by-step explanation:
Txbx3 expand-
3 (t * b)
*= times btw
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.
The two numbers are 14 and 11
Answer:
In explanation down below.
Step-by-step explanation:
So if the boat was able to travel 27 miles in 2 hours that means that it traveled 13.5 miles an hour. I think that you want to know how many miles the boat will travel in 1/2 an hour. Which is 6.75.
1 hour: 13.5 miles
1/2 hour the boat has traveled 6.75 miles.
I hope this helps!!!
Please mark brainliest :)
add 4 each time
the nth term is a_n or f(n)
the next term after that is a_{n+1} or f(n+1)
so each term is 4 more than previous
basically
a_{n+1}=4+a_n or
f(n+1)=4+f(n)
same thing
