It is the last one.
A pre-image is the original before another shape is created from it, either dilated, translated, reflected, or rotated.
6 + 3q + 306 + 153q + 15
156q + 327
Angle bisector would be the answer
4^-3
You first need to make the exponent positive. To do this put it in a fraction.
1/4^3
Now solve the exponent.
4 * 4 * 4 =
^
16*4 = 64
1/64 is your answer
X shortest piece
X+6 middle piece
X+8 longest piece
Add them
3x+14=56
3x=42
X=42/3=14
