Issouf claims that the scale factor is 1/2. which statement about his claim is correct? a- he is correct because cb is 4 and c' b' is 2. the scale factor is c'b'/cb = 2/4 = 1/2b- he is correct because he needs to subtract 2 from each side. a reduction has a scale factor that is a fraction, so it must be 1/2c- he is incorrect because it is 3. cb is actually 2+4 or 6. so one needs to multiply the pre-image length by 3 to get the image; 3 is the scale factor.d- he is incorrect because the scale factor is 1/3. cb is actually 2 + 4 = 6. cb is the pre-image, so the scale factor is c'b'/cb = 2/6 = 1/3.
