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...? If I am right can you show your work please...I am just starting to understand these..thank you

Correct!

To answer this, we need to know the expression for the area of a square which is the square of its side length or:

Area = a²

Solving for the side length,

a = √area
a = √144x²
a = 12x

Therefore, the side length is 12x.

You just said that the + with a line under it was correct now your saying that 12x is correct which one is the right one.

If your doing this in conexus with Mrs. Martin it’s no solution. Idk why, but it is.

Nvm it’s B, sorry.

To find the side length of a square with a given area, you need to take the square root of the area. In this case, the area is 144x².

To find the square root, you can use the property that the square root of a product is equal to the product of the square roots. Therefore, you can express the given area as (12x)².

Taking the square root of (12x)² will give you the side length of the square. So, the square root of (12x)² is simply 12x.

Therefore, the correct answer is B. 12x.

Let me know if you need further clarification.
