2x-3y=4
x+4y=-9/*(-2)
2x-3y=4
-2x-8y=18
-11y=22/:(-11)
y=-2
x+4*(-2)=-9
x-8=-9
x=-1
I hope this helped.
Answer:
x=2.4
Step-by-step explanation:
as the 2 triangles are similar,

therefore ;


Given:
The expression is
![\sqrt{\sqrt[3]{6}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Csqrt%5B3%5D%7B6%7D%7D)
To find:
The simplified form of the given expression.
Solution:
We have,
![\sqrt{\sqrt[3]{6}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Csqrt%5B3%5D%7B6%7D%7D)
Using the properties of radical and exponent, we get
![[\because \sqrt{x}=x^{\frac{1}{2}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%5D)
![[\because \sqrt[n]{x}=x^{\frac{1}{n}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%5Bn%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%5D)
![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)

Therefore, the correct option is A.
