Answer:
Step-by-step explanation:
Subtract the like terms:
6x^2 - 2x^2 = 4x^2
3x - -4x = 3x+4x = 7x
1 - 5 = -4
Now combine them to get the final answer:
4x^2 + 7x - 4
Well, anything that's rotated (turned), reflected (flipped), or translated (moved) is still the same shape of the same size, so the new figures would be congruent with the originals. Dilation, however, is when the shape stays the same but the size changes, so when a figure is dilated, it's not congruent, just similar. 2 out of the 4 are dilated, so those ones would be the answer.
