Figure B is a scale image of Figure A, as shown. Enter the scale factor applied to Figure A to produce Figure B: figure A, 3 2 4 and Figure B, 6 4 8

Answer:
1:2
Step-by-step explanation:
3x2=6
2x2=4
4x2=8
Multiplying all sides by two (or doubling all sides) gets the first triangle to the size of the second (or produces the second image).
So you know 2 is the answer, I am not sure how to write the scale factor maybe it is 1:2.
