I believe it would be a 100 correct me if I’m wrong since every one box equals 20 books 5 boxes would contain 100.
For this case we have, by definition, a function is given in the form:

Where x is the independent variable and y is the dependent variable.
If we have:

We can rewrite it in the following way:

Comparing with the generic definition of a function, we have that
Answer:
A relation that could be rewritten using function notation is option b.

Answer:
You either need two sides and the angle between them or two angles and the side between them. Otherwise, you can construct a family of triangles that include the given pieces.
Step-by-step explanation:
"How do you find the missing sides of a triangle?"
I'm not a mathematician, but it seems to me that no one can find the missing sides (note the plural: "sides") of a triangle by having just one -- or none. You need at least two sides to get an answer...
Answer:
12
Step-by-step explanation:
11 doesn't go into any numbers because it is prime, same with 17. 15 only goes into 3 and 5 so that's not it either. 21 only goes into 3 and 7, 26 doesn't go into 4 nor 6. 4 doesn't go into 30 evenly, so that leave just 10 and 12. 3,4,nor 6, go into 10. That leaves only 12 as the final answer.
