Answer:
see explanation
Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ± 
= ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ± 
hi again uwu
Answer: i know that the moon rises in the east, and takes 27 1/3 days to go around the earth....
Step-by-step explanation:
because every time Earth spins around once the moon moves about 13 degrees east along its orbit.Thus, the Earth must rotate an extra 13 degrees more each day for a point on its surface to be roughly under the moon again. since earth takes about 50 minutes to spin 13 degrees the moon rises about 50 minutes later each day and sets about 50 minutes later too.
