Answer:
D: 21
Step-by-step explanation:
The first term is (a1). The third term is (a1)r². The product of these terms is ...
(a1)(a1)r² = ((a1)r)², the square of the second term.
The missing term is √(7·63) = √441 = 21.
_____
<em>Additional comment</em>
In consideration of the above, you can also see that the common ratio can be found from ...
a3/a1 = ((a1)r²)/(a1) = r² = 63/7 = 9
Then the common ratio is r = √9 = 3, and the second term is 7·3 = 21.

Step-by-step explanation:
We have been given a graph of a quadrilateral and we are asked to find the coordinates of our quadrilateral after reflecting it across the x-axis.
We can see that coordinates of quadrilateral ABCD are:
A (-1,4),
B (-5,8),
C (-5,4),
D (-4,2).
Since we know that rule for reflecting an image across x-axis is . This means that y-coordinates of our given image will be negative.
So after reflecting our given quadrilateral across x-axis, coordinates will be:
