Answer:
Fourth term:
=
= 
Fifth term:
=
= 1
Sixth term: 
Step-by-step explanation:
The geometric progression is:

The first term, a, is 9
To find the common ratio, r, all we have to do is divide a term by its preceding term.
Let us divide the second term by the first:

That is the common ratio.
Geometric progression is given generally as:

where a = first term
r = common ratio
= nth term
We need to find the 4th, 5th and 6th terms.
Fourth term:
=
= 
Fifth term:
=
= 1
Sixth term: 
Answer:
D(3;-2).
Step-by-step explanation:
1) 
2) according to the formulas above:

3) finally, D(3;-2).
Answer:
(x+9)(x-9)
Step-by-step explanation:
Find distance of side = (y₂- y₁) / (x₂- x₁)
you can get length and width
then area = length * width
perimeter = 2 * (length + width)
