What is the side length of a square with an area of 144x²?
A.12
B.12x
C.±12x
D.no solution

I think it is C...?
Answered by Lena
I would also go with C because:

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

Answered by Lena
You've got me stumped on this one too. I hope you understand why it's option B because I have no idea.
Answered by Jeremy
The square root of 144x is 12x

You are WRONG.
Answered by Kim
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
Answered by Kandi
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 :)
