Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
- (2 + 3i) + (3 - 4i)
- <u>5 - i</u>
<u>Question 2</u>
- (3 – 5i) – (–2 – i)
- 3 - 5i + 2 + i
- <u>5 - 4i</u>
<u>Question 3</u>
- (2 − 4i)(1+ 3i)
- 2 - 4i + 6i - 12i²
- <u>14 + 2i</u>
<u>Question 4</u>
- 2i(-1 + 3i)
- -2i + 6i²
- <u>-6 - 2i</u>
Step-by-step explanation:
when a line intersects with 2 (or more) parallel lines. then, of course, the intersection angle is the same with every of the intersected lines. otherwise they would not be parallel.
so,
7x - 10 = 60
7x = 70
x = 10
Answer:
60
Step-by-step explanation:
750÷12.5=60
Convert 12 and a half hours into a decimal.=12.5
You would divide the 750 by the 12.5.
1. Definition of Parallelogram
2. Angle 2 plus Angle 3 is 180=Def of Supple
3.Angle Congruence Postulate
4. Angle 1 and Angle 3 equal to 180
Answer:
-7
Step-by-step explanation:
you divide both sides by -2 and 14/-2 is equal to -7
