-b can never be a positive number. If a number has a dash like that in front of it it is negative
A would be the correct answer
Hope that helps
The answer is 122 it’s basically the same rounding with whole numbers
The value of k are -5 and -7 if the distance between points (2,k) and (0,−6) is √5
<h3>What is a distance formula?</h3>
It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:

The question is:
Given the points (2,k) and (0,−6), for which values of k would the distance between the points be √5

5 = 4 + (6 + k)²
After solving:

(6 + k)² = 1
k = -5 or -7
Thus, the value of k are -5 and -7 if the distance between points (2,k) and (0,−6) is √5

Answer:
0.220 L
Step-by-step explanation:
One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:
2.220 L - 2 L = 0.220 L

The nice thing about metric units is that conversion factors are often powers of 10, so only movement of the decimal point is required. It can be worthwhile to become familiar with the SI prefixes.
