Step-by-step explanation:
Answer:
b
Step-by-step explanation:
We can find the length of the ladder by squaring the known digits, adding them, and finding the square root of the sum. This would mean our first equation, after squaring, will look like this:
49+81=130
Now that we have <em>c</em> squared, we can go through and find the approximate square root, which is 11.4. That would mean the ladder is 11.4 meters long.
If they are looking to have them all simplified, this is how they should look.
4y - 4
4y + 4
4y + 1
