The third one and forth one are right.
ANSWER:
<u>On solving equation by quadratic formula method, we get</u>
D = b² – 4ac
- (–5)² – 4 × 1 × 3
- 25 – 12
- 13
D > 0, so it has real roots.
Now, x = – b ± √D/2a
So, <u>Correct choice</u> - [A] & [C].
Answer:
Change the angle measures to 90°
Step-by-step explanation:
A rhombus (which is what you have as you marked the edges congruent) has the diagonals perpendicular. Therefore, you need to change the angle measures to 90°
20 because for all regular polygons their exterior angles add up to 360, so 360\18 =20
