Can you pls help me with the first 2 thank you

Answer 1

We will have the following:

10. We determine the individual cost for each of the 10, that is:

`(25)/(10)=2.5`

So, you will be saving $0.50 per book.

11. We will have that the length of the segment that connects vertex T to vertex V is:

`d_(TV)=\sqrt[]{(6-1)^2+(2-2)^2}\Rightarrow d_(TV)=5`

So, the segment has a length of 5 units.
