Answer:

23 blocks

Explanation:

Answer:

17 blocks

Explanation:

Because this will create a right triangle, you can find this using the Pythagorean Theorem.

A quick refresher (Or a lesson if you haven't learned this yet), the equation for the Pythagorean Theorem is a^2+b^2=c^2. A and B are the sides that make up the right angle and can be used interchangeably. C is the other side and the one we are going to find.

Let's first plug-in the numbers we already know.

a^2+b^2=c^2 -> 15^2+8^2=c^2

We'll then calculate 15^2 and 8^2

You'll find that this equals 225 and 64.

You now have 225+64=c^2

Add 225 and 64,

289=c^2

The final step is to simplify c^2 into c. You will have to square c^2 and because of that must also square 289

[tex]\sqrt{289} =\sqrt{c^{2} }[/tex]

17=c

c=17

You now have your answer, Carmen walked 17 blocks to get back to her starting point.
