Answer: LAST OPTION.
Step-by-step explanation:
1. You have the following equation:
![6x^{2}=54](https://tex.z-dn.net/?f=6x%5E%7B2%7D%3D54)
2. Then you must solve for x, as following:
![x^{2}=54/6\\x^{2}=9\\x=\sqrt{9}\\x=+/-3](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D54%2F6%5C%5Cx%5E%7B2%7D%3D9%5C%5Cx%3D%5Csqrt%7B9%7D%5C%5Cx%3D%2B%2F-3)
Therefore, as you can see above, the answer for the exercise is the last option.
