find the product of (x − 7)2.
x2 − 14x + 49
x2 + 14x + 49
x2 − 49
x2 + 49

x^2 - 14x + 49.

Step-by-step explanation:

(x − 7)^2

= (x - 7)(x - 7)

= x(x - 7) - 7(x - 7)

= x^2 - 7x - 7x + 49

= x^2 - 14x + 49.

x−7)(2)

=(x+−7)(2)

=(x)(2)+(−7)(2)

=2x−14 + 49

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
