Plll halp ! a large ship is built with 87 rooms on each level. the ship has 4 levels. which pair of expressions shows two ways to determine the total number of rooms on the ship? a) 80 × 4 and 80 × 7 b) 87 × 4 and 80 × 4 c) (87 × 4) + (7 × 4) and 4 + 4 + 4 + 4 d) (80 × 4) + (7 × 4) and 87 + 87 + 87 + 87 thx

The answer is C

hope this helps

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
