Answer:
2x(x + 3)
Step-by-step explanation:
Given
2x² + 6x ← factor out the common factor 2x from each term
= 2x(x + 3)
Try this website, I don't know too much about this stuff but I found a website that explains by text and video. http://www.statisticshowto.com/how-to-use-a-probability-tree-for-probability-questions/
Answer:
8.789120
(you have to include the zero, or else the answer would no longer be the nearest millionth! and you would be marked wrong)
Log y=9.
e
Drop first and make it logs base.
Y sits beside it
And 9 becomes answer
Therefore e = certain #
And to the power (which is Y) will give you answer of 9
Answer:
- Both have 4 imaginary roots
Step-by-step explanation:
1)
1.
- x^2 + 9 = 0
- x^2 = - 9
- x = ± √-9
- x = ± 3i
2.
- x^2 + 6 = 0
- x^2 = -6
- x = ±√-6
- x = ± i√6
It has 4 imaginary roots and no real roots
2)
1.
- x^2 + 7 = 0
- x^2 = -7
- x = ± √7
- x = ± i√7
2.
- x^2 + 5 = 0
- x^2 = - 5
- x = ± √-5
- x = ± i√5
It has 4 imaginary roots and no real roots
