A way you can check if 7 is a factor of 72 is divide 72 by 7 and check if your answer is a whole number.

72 / 7 = 10.2857...

Since this is not a whole number, 7 is not a factor of 72.

Have an awesome day! :)

Multiply √2 by √72. The product is a rational number because √144 can be simplified to an integer.

Step-by-step explanation:

As Landon has to prove that two product of two rational numbers, he has to choose two rational numbers from the list and then multiply and show that the product is also a rational number.

Let us define the rational numbers first

A number that can be written in the form of p/q where p,q are integers and q is not equal to zero, is called a rational number.

From the give =n list of rational numbers

Taking

√2 and √72

$\sqrt{2} * \sqrt{72}\\=\sqrt{2*72}\\=\sqrt{144}\\=12\\=\frac{12}{1}$

As we can see that the product of √2 and √72 is 12 which is also a rational number.

So,

Multiply √2 by √72. The product is a rational number because √144 can be simplified to an integer.

A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation

Eduardwww [97]

Pls see answer below.

Step-by-step explanation:

In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.

Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.

Hope this helped.
