Answer:
n5 + 17
Step-by-step explanation:
They're asking for a pattern.
17 + 5 = 22
22 + 5 = 27
27 + 5 = 32
So it starts at 17 and increases by five each time.
The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.
n5 + 17
A(b+c)=ab+ac
we have
9(72)=9*?+9*2
c=2
sub, but it must be equal to minus 2 from 72
7(70+2)=9*70+9*2
the question mark is 70
and the restult of the equation is 648
?=70
Answer:
6
Step-by-step explanation:
Difference between n and 3 is 3-n
Multiplied by -6: -6(3-n)
-6(3-n) = 18
3-n = -3
n = 3+3 = 6
Answer:
1.627 miles
Step-by-step explanation:
Longest distance: 2.55 miles
Shortest distance: 0.923 miles
