Question

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:

$\frac{25}{10}=2.5$

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.
