Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides (\sqrt{x} this symbol). When you do that, you should get what x is! Let me know if you still need help!

<h3>Answer:</h3>

±9

<h3>Step-by-step explanation:</h3>

<u>We are given the equation:</u>

x² - 11 = 70

<u>Solving for x:</u>

x² - 11 = 70

x² = 81                                                          [adding 11 on both sides]

x = ±√81                                                 [taking the square root of both sides]

x = ±9

frutty [35]
<span>With the variable "y" being used to represent the total cost of going to the park for a year, the first equation would read "y = 50" since it is a one-time, flat cost. The second equation would be "y = 4x", with "x" being used to represent the number of times the person visited the park during the year multiplied by the $4 cost per visit.</span>

LuckyWell [14K]
If you're evaluating, then multiply by the conjugate and simplify.
= -1 -i
The answer would be the same even if you divided...and or, wrote it in simplest form.
