Which series of transformations can be used to prove that Ax'Y'Z' is congruent to Axyz, as shown by the graphs below? D
rotate AXYZ 90° counterclockwise about the origin and then translate it 8 units to the right
о
reflect AXYZ across the line y = -x and then translate it 4 units to the left
rotate AXYZ 90° clockwise about the origin and then reflect it across X'Y' that resulted from the rotation

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
