The polygons above are similar. find x and y. the images are not drawn to scale.

a.
x = 15, y = 18
b.
x = 18, y = 14
c.
x = 18, y = 16
d.
x = 21, y = 14

X=21 and y=14
Here is how I got it I found out the ratio of the sides that measured 18 and 12
the ratio was 3:2 so I divided 27 by 1 1/2 and I got 18 but since the equation for x was x-3 all i had to do was 21-3=18 so x=21 and i did the same thing with Y

The correct answer will be d. -4

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
