I marked my answers, if they are not right please explain why, I need to get these right to keep my grade up.
for this particular question
6: is D (AC, AB,BC)
7:D. (15 cm, 9 cm, 24 cm)
i took the test and these are correct.
Well Amber, you didn't help xD come to think of it neither did I.
Ok I think I might have it right
6. D
7. C
