Y=4 is going to be the answer.
Using the Pythagorean theorem we get:
![y^2+8^2=12^2.](https://tex.z-dn.net/?f=y%5E2%2B8%5E2%3D12%5E2.)
Simplifying the above result we get:
![y^2+64=144.](https://tex.z-dn.net/?f=y%5E2%2B64%3D144.)
Subtracting 64 from the above equation we get:
![\begin{gathered} y^2+64-64=144-64, \\ y^2=80. \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%5E2%2B64-64%3D144-64%2C%20%5C%5C%20y%5E2%3D80.%20%5Cend%7Bgathered%7D)
Therefore:
![y=\sqrt{80}\approx8.9.](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B80%7D%5Capprox8.9.)
Answer:
Answer:
The answer is "
".
Step-by-step explanation:
Given value:
![\to \frac{2 \frac{7}{8}}{2 \frac{1}{4}}](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7B2%20%5Cfrac%7B7%7D%7B8%7D%7D%7B2%20%5Cfrac%7B1%7D%7B4%7D%7D)
They understand that, by using algebraic expressions laws, they subtract that inverse whenever we subtract powers with the same base. Every exponent's core is 2, therefore we subtract:
![\to \frac{7}{8} - \frac{1}{4}](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7B7%7D%7B8%7D%20-%20%5Cfrac%7B1%7D%7B4%7D)
They have a shared denominator. It's least that is equally divided
among 8 or 2 is 8:
![\to \frac{7}{8} - \frac{2}{8}\\](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7B7%7D%7B8%7D%20-%20%5Cfrac%7B2%7D%7B8%7D%5C%5C)
![\to \frac{7-2}{8}\\\\\to \frac{5}{8}\\\\](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7B7-2%7D%7B8%7D%5C%5C%5C%5C%5Cto%20%5Cfrac%7B5%7D%7B8%7D%5C%5C%5C%5C)
This gives us:
![\to 2 \frac{5}{8}](https://tex.z-dn.net/?f=%5Cto%202%20%5Cfrac%7B5%7D%7B8%7D)
As rational notation is written as extremists, that root was its denominator as well as the power seems to be the numerator.
Which means 8 is the root and 5 the force that gives us:
