Answer:
Step-by-step explanation:
The first step is to multiply the fraction by (3 +3i) / (3 +3i) to delete the i terms from the denominator:
It has line symmetry and rotational symmetry, so A is the answer, hope this helps
Answer:
63
Step-by-step explanation:
so y/3 - 9 = 12, add 9 on both sides and you get y/3 = 21. Then you multiply both sides by 3, y/3 * 3, the 3's cancel out, 21 * 3 = 63. You get y = 63
So basically just do + 9 on both sides then *3 on both sides (do it step by step)
