Answer: 14

Step-by-step explanation:

Substitute both K and M for its respective numbers.

I got this equation after substituting.

0.3(20) - 4(-2)

Simplify:

6 - (-8)

When we subtract by a negative number, the sign switches from (-) to (+)

So we're left with

6+8 which is 14.

The expression above should be further simplified for which value of x?

stellarik [79]

Answer: A) 35

Step-by-step explanation:

We have the following:

$\sqrt{215 x}$

Now, $215$ is made up of two factors, $43$ and $5$ :

$215=(43)(5)$

So, we have to choose a number for x containing a factor of $43$ and or $5$ . In this case, the best option is $35=(7)(5)$ :

Hence:

$\sqrt{215 (35)}=\sqrt{(43)(5)(7)(5)}$

$\sqrt{215 (35)}=\sqrt{(25)(43)(7)}=\sqrt{25} \sqrt{301}$

Finally:

$\sqrt{215 (35)}=5 \sqrt{301}$
