Remark

An anion is a charged ion that has taken on electrons. So you are talking about an activity that definitely involves electrons. It would seem reasonable to believe that the increase in the size of an ionic radius is caused by an increase in the number of electrons in the valence (outside) ring. The statement is true.

Answer:

1 cm

Step-by-step explanation:

To solve this problem we can use the Pythagorean theorem. In fact the diagonal of a rectangle is an hypotenuse of a right triangle, while the length is a leg. The width is the other leg

width = √2^2 - (√3)^2 = √4 - 3 = √1 = 1 cm

Which numbers are a distance of 4 units from 7 on the number line?

gayaneshka [121]

On the number line, 3 and 11 are the numbers that are a distance of 4 units from 7..

On there are two types of numbers one is a positive and the other is a negative number. These two are separated by the number zero which is known as the origin. Positive numbers are on the right side of the origin and negative numbers are on the left side of the origin on the number line.

We have been asked the numbers which are a distance of 4 units from 7 on the number line.

For that, we will first add 4 to the number 7, that is,

4 + 7 = 11

Thus, number 11 is a distance of 4 units from 7 on the number line if we move to the right side from 7.

Now we will subtract 4 from the 7 we will get,

7-4 = 3

Thus, Number 3 is a distance of 4 units from 7 on the number line if we move to the left side from 7.

Hence 3 and 11 are the numbers that are a distance of 4 units from 7 on the number line.

6x + y = -2<br> y= -3x + 1<br><br> Graph the solution

Gala2k [10]

6x + y = -2
y = -3x + 1

Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1

Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4

Coordinates would be: (-1,4) Mark that point and join with origin.

Hope this helps!
