Which of the following is equivalent to (x + 4)(3x2+2x)?
O
A. (x+4)(3 x2)+(x+4)(2x)
O
B. (x+4)(2x)+(x+4)(3x)
O
c. (x+4)(2x)•(x + 4)(3x)
O
D. (x + 4)(3x?)•(x+4)(2x)

c. (x+4)(2x)•(x + 4)(3x)

Step-by-step explanation:

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
