Answer:
73, 74, 75
Step-by-step explanation:
So the sum of three consecutive integers is 222.
Let's let the first integer be n.
Then the second integer <em>must</em> be (n+1).
And the third integer must be (n+2).
They total 222, thus:

Combine like terms:

Subtract 3 from both sides:

Divide both sides by 3:

So, the first integer is 73.
So our sequence is 73, 74, and 75.
And we're done!
Answer:
Using the formula for the distance between two points, which is generated using coordinates and absolute value, we find that the distance between these two points is of 9 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points,
and
. The distance between them is given by:

This formula is generated using coordinates and absolute value.
In this question:
(3,-7) and (3,2). So

The distance between these two points is of 9 units.
