Imagine you're a British mathematician in WW2, during an attack 7 german tanks were defeated and captured, then they found the numbers of each one ( 10, 13, 110, 138, 147, 284, 323 ). How can I estimate the number of tanks that Germans have?

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

i believe the answer is c.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
