What happens if you divide each term of `(5x + 10x(15x))/(20x)` by 5x?

The 5x goes away, the 10x becomes 2, the 15x becomes 3, and the 20x becomes 4.

The 5x becomes 1, the 10x becomes 2, the 15x becomes 3, and the 20x becomes 4.

The 5x goes away, the 10x becomes 2, the 15x stays the same, and the 20x becomes 4.

The 5x becomes 1, the 10x becomes 2, the 15x stays the same, and the 20x becomes 4.

Which of the following equations is valid?

`sqrt((9x^2)(y^2)) ＝ (3x)(y)`

`2(9x^2)(y^2) ＝ (18x^2)(2y^2)`

`sqrt((9x^2)+(y^2)) ＝ (3x)+(y)`

All of these are valid.
