To solve this plug 2 in for d in the equation like so:

The fraction
can be simplified to 2.
How I found this:
The greatest common factor of 8 and 4 is 4.
If we divide 8 by 4 you get 2
If you divide 4 by 4 you would get 1
That gives you the simplified fraction:
Which is the same as simply 2
Now we have the expression:
2 - 2
^^^ A number subtracted from itself is always zero
The answer is:
0
Hope this helped!

Two polygons are similar if their corresponding angles are congruent and their sides are in proportion.
The sides could be in a ration of 1:1 in which case the two hexagons have corresponding sides that are congruent, but they do not have to be. It could be the case that the sides of one are twice the length of the other so the ratio is 2:1. In this case the hexagons have the same shape but not the same size.
So the answer is this, the corresponding sides of similar hexagons may be congruent but do not have to be.
Multiply the first equation by 3 and the second equation by 2:

Subtract the two equation to get rid of the x variable:

Use the value of y to determine the value of x: for example, using the first equation we have
