8 because 7 is closer to 5 so you round up
So remember that the distance formula is 
.
1.
Distance between (4,-5) and (4,-2) is 3 units.
2.
Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
N+d=21
5n+10d=170
so
multiply first equation by -5 and add to other one
-5n-5d=-105
<u>5n+10d=170 +</u>
0n+5d=65
5d=65
divide both sides by 5
d=13
sub back
n+d=21
n+13=21
minus 13 both sides
n=8
