Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
<h3>

</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-7,-2) and (11,3)
The distance between the points is
<h3>

</h3>
We have the final answer as
<h3>

</h3>

If you had one row, you would have 22 chairs.
If you had two rows, you would have 22+22=44 chairs.
If you had three rows, you would have 22+22+22 chairs, or 66 chairs.
See the pattern?
If you had 40 rows, you would add 22 40 times, or 22*40=880 chairs.
Hope this helps!
