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.

Find the hypotenuse (c) of the right triangle.

Aleksandr-060686 [28]

<h2><u>Solution</u>:-</h2>

Hypotenuse (x) of the right triangle = $\sqrt{7² \: + \: 11²}$

Hypotenuse (x) of the right triangle = $\sqrt{49 \: + \: 121}$

Hypotenuse (x) of the right triangle = $\sqrt{170}$

Hypotenuse (x) of the right triangle = 13

The hypotenuse (x) of the right triangle is <u>1</u><u>3</u><u> </u><u>m</u>.

<h3>Hence, option (D) <u>1</u><u>3</u><u> </u><u>m</u> is correct. [Answer]</h3>

What is the answer X=-2(6+4)

Digiron [165]

Answer:

X = -20

Step-by-step explanation:

X = -2(6+4)

^ add 6 and 4 together first because they are in parentheses

-2(10)

^ this parenthesis means you want to multiply -2 and 10

because 2 x 10 = 20

that must mean -2 x 10 = -20

therefore, the value of X is -20

X= -20
