Please help me. I'm not trying to guilt-trip or anything but I suck at school and my questions haven't been answered or people just forget that there are multiple photos. I hope someone will help me. I only have 10 points :l I know the links are scams

A= 9 , B= 4 , C= 18

Step-by-step explanation:

if u need a in depth explanation text me in the comments :)

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
