Hello from MrBillDoesMath!
Answer:
Choice D, x = +\ sqrt(121)
Discussion:
x^2 = 121 => take square roots of both sides
x = +\- sqrt(121) => as sqrt(121) = +\- 11
x = +\- 11
The closest answer is D as it includes both values of x, unlike choices A and B which include a single value of the square root
Thank you,
MrB
