Answer:
value was â€"4. Which could be Arianna’s original expression? One-sixth (negative 3 x minus 24) One-sixth (negative 5 x minus 8) One-sixth (negative 10 x minus 4) One-sixth (negative 12 x minus 16).
The <span>Pythagorean Theorem tells us that
![a^{2}+b^{2}=c^{2}](https://tex.z-dn.net/?f=%20a%5E%7B2%7D%2Bb%5E%7B2%7D%3Dc%5E%7B2%7D)
where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:
![b=\sqrt{c^{2}-a^{2}}](https://tex.z-dn.net/?f=b%3D%5Csqrt%7Bc%5E%7B2%7D-a%5E%7B2%7D%7D)
We can then substitute known values, and solve:

![b=\sqrt{10^{2}-8^{2}}](https://tex.z-dn.net/?f=b%3D%5Csqrt%7B10%5E%7B2%7D-8%5E%7B2%7D%7D)
![b=\sqrt{100-64}](https://tex.z-dn.net/?f=b%3D%5Csqrt%7B100-64%7D)
![b=\sqrt{36}](https://tex.z-dn.net/?f=b%3D%5Csqrt%7B36%7D)
Answer:
20c+14
Step-by-step explanation:
To find the perimeter we have to add up all the sides
4c+6c+7+4c+6c+7
Combine light terms
20c+14
