2g(4g+3)+g(g-7) expand linear brackets​

7g^2 - 13g

Step-by-step explanation:

2g(4g+3)= 8g^2 + 6g

g(g-7)+ g^2 - 7g

8g^2 + 6g = g^2 - 7g

7g^2 = -13g

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
