Answer:
the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.
Step-by-step explanation:
this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.
you can check with the ceaser method as well, but you're still going to find the same solution.
plus, for example, if it takes 7 grams of sugar to make 1 cake, it wouldnt make sense for 1 gram of sugar to make 7 cakes.

To put it in the simplest words :
Get rid of the parentheses and add like so:
<span>Combine like terms
2n^3+n^3= 3n^3
-8n^2 remains the same since there are no like terms for it
8n also remains the same
-9+7=-2
Put all of the numbers together
3n^3-8n^2+8n-2
Final answer:
B - the 2nd one</span>
