Answer:

$\large\boxed{d=3\sqrt5}$

Step-by-step explanation:

$\text{the formula of a distance between two points}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2):\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=========================\\\\\text{We have}\ (4,\ 9)\ \text{and}\ (-2,\ 6).\ \text{Substitute:}\\\\d=\sqrt{(-2-4)^2+(6-9)^2}=\sqrt{(-6)^2+(-3)^2}=\sqrt{36+9}=\sqrt{45}\\\\\sqrt{45}=\sqrt{9\cdot5}=\sqrt9\cdot\sqrt5=3\sqrt5$

Answer:

<em>Answer: B. It is a perfect square</em>

Step-by-step explanation:

<u>Radical Expressions</u>

Melissa multiplied $\sqrt{a}$ and $\sqrt{b}$ and got a rational number.

We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.

We can write that product like:

$\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}$

If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

Answer: B. It is a perfect square
