(33x3)+(33x3)= blah blah blah sorry it had to be 20 characters long ;)

198

Step-by-step explanation:

due to order of eliminations u multiply 33 and 3 in both parantheses. then you add them together, you get 198.

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
