Answer:

The correct answer is 2,4,6,8 and 0.

Step-by-step explanation:

A number is considered a multiple of 2 when it contains the number 2 repeated several times.

For example the number 8, contains the number 2 repeated 4 times = 2 + 2 + 2 + 2 = 8

It can also be a multiple of 2, any number multiplied by two. For example 6 is a multiple of 2 since 2x3 = 6

In simple words, all even numbers, or all numbers multiplied by 2, are multiples of 2.

2x0 = 0

2x1 = 2

2x2= 4

2x3 = 6

2x4 = 8

2X5 = 10 ...

Answer:

Step-by-step explanation:

Angles 1, 2, and 3 are supplementary (they add up to equal 180). If angles 1 and 3 are 20 each, then their sum in 40, making angle 2

180 - 40 = 140. If this central angle is 140 degrees, then the measure of the arc that it cuts off also measures 140 degrees. This is not to be confused with the arc length, which is not even remotely the same thing!

Find the solution of 3 times the square root of the quantity of x plus 6 equals negative 12, and determine if it is an extraneou

Anna35 [415]

For this case we have the following equation:
$3 \sqrt{x+6}=-12$
Rewriting we have:
$\sqrt{x+6}= \frac{-12}{3}$
$\sqrt{x+6}=-4$
We raise both members of the equation to the square:
$(\sqrt{x+6})^2=(-4)^2$
Rewriting we have:
$x+6=16$
$x=16-6$
$x=10$
It's a extraneous solution because equality is not met by substituting x = 10 in the original equation:
$3 \sqrt{10+6}=-12$
$3 \sqrt{16}=-12$
$3(4)=-12$
$12=-12$
Answer:
The solution is:
$x=10$
It's a extraneous solution
