PLEASE HELP DUE 11:59PMDavid and Dora are close friends studying in the same school. David's home is 6.87 miles away from school. Dora's home is 7 times as far as David's home from school. find the distance between Dora's school and her home

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
