n = - 2
Step-by-step explanation:
Given
- 6n - 2n = 16, that is

Simple interest
you can charge it monthly or yearly
find 4% and multiply by how many months or years
4% of 900=
0.04 times 900=36
that is each time the interst is added
if it is monthly, (6months so ) 6 times 36=216
if it is yearly (6months=1/2year so )6 times 1/2=3
if it is taken monthly, then Sam earns $216
if it is taken yearly, then Sam earns $3
if its diameter is 14, then its radius is half that or 7.
