What is the side length of a square with an area of 144x²?

I would also go with C because:

(-12x)(-12x) = 144x^2
(12x)(12x) = 144x^2

Thank you...

It was wrong - it was B...thanks anyhow

You've got me stumped on this one too. I hope you understand why it's option B because I have no idea.

The square root of 144x is 12x

You are WRONG.

Cassie,

It is C unless the domain of x is restricted to positive values. In that case it is B.
The computer or teacher is incorrect based on the information shown here. Why? Well if x =-1, Choice B gives us side= 12*(-1) which is -12. A square cannot have a length of -12. Therefore we’d use -12x for negative values of x.
So it’s not a properly worded question which has led to all the confusion.

I dont understand

C would be correct if we weren't trying to find the length of a shape. but because the length of a side cannot be negative, the correct answer is B :)

Before all answers, it is B. Its B because.... well 144x^2 turns into (12x)(12x)

super simple smh.
1. C
2. D
3. B
4. B
5. C
