Which composition of transformations will create a pair of similar, nol congruent triangles? O a rotation, then a reflection
O a translation, then a rotation
O a reflection, then a translation
O a rotation, then a dilation

Rotation then dilation.

Step-by-step explanation:

Dilation changes the size. So the result is a similar not congruent triangle. The other transformations move the figure around on the plane.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
