Answer:
3 and 4
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size so here reducing a photograph to half its dimensions and enlarging a photograph to double the dimensions is dilation.
=> For dilation, we use a certain scale factor
=> In the 3rd option, scale factor is 1/2
=> In the 4th option, scale factor is 2.
A^2 -121 = a^2 -11^2 = (a-11)(a+11)
so the second choice is right sure
