Step-by-step explanation:
A parallelogram is a flat shape that has four sides. The two sets of opposite sides are parallel and of equal length to each other.
To prove that our figure is a parallelogram we first get the slope of our sides.
The formule we use to get the slope is:
m = 
- first we have the W-Z side that it's supossed to be parallel to X-Y side
if we use our formule to calculate the slope of W-Z:
=
= 8
if we use our formule to calculate the slope of X-Y:
=
= 8
- We know that parallel lines will never intersect because they have the same slope, therefore W-Z side is parallel to X-Y side
2. Then we have the W-X side that it's supossed to be parallel to Z-Y side
if we use our formule to calculate the slope of W-X:
=
if we use our formule to calculate the slope of Z-Y:
=
- We know that parallel lines will never intersect because they have the same slope, therefore W-X side is parallel to Z-Y side
Then we have to prove that the parallalel sides are equal length to each other.
The formule we use to get the distance between two points is:

We calculate the lenght of the W-Z side that it's supossed to be equal to X-Y side:
W-Z =
= 
X-Y =
= 
So the W-Z side have the same lenght to X-Y side.
We calculate the lenght of the W-X side that it's supossed to be equal to Z-Y side:
W-X =
= 
Z-Y =
= 
So the W-X side have the same lenght to Z-Y side.

Answer:
37 years.
Step-by-step explanation:
Interest = PRT/100 where P = Initial Amount, R = rate, T = the time.
So we have the equation:-
8600 + 8600*3.95 * T / 100 = 21000
8600 + 33970T / 100 = 21,000
8600 + 339.7T = 21000
339.7T = 21000 - 8600
T = (21000 - 8600) / 339.7
T = 36.5 years
