A, 25 + 7b x 9b - 83
b, 10 x 7b - 9b x 83
c, 25 x 7b - 9b + 83
d, 10 + 7b + 9b divided by 83
5 to the second power x 7b - 9b + 83 = ?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
