Answer
x - 1 + 6x^2
Step-by-step explanation:
Write al the sides together: 2x + 5 + x^2 - 6 + 4x^2 + 2x + x^2 - 3x
Then organize the terms: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
Simplify: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
2x + 2x -3x = 4x - 3x = 1x or x
x + 5 - 6 + x^2 + x^2 + 4x^2
5 - 6 = -1
x - 1 + x^2 + x^2 + 4x^2
x^2 + x^2 + 4x^2 = 2x^2 + 4x^2 = 6x^2
x - 1 + 6x^2
Answer:

Step-by-step explanation:
we are given
- Amplitude:7
- Period:9π
- Phrase shift:¼
remember that,

where A is the Amplitude
B is the Period
C is the Phase shift
D is the vertical shift
note that, since D isn't given we'll take it 0
altogether substitute:

hence,
our equation is

and we are done!
Answer:
Water (one oxygen atom bonded to two hydrogen atoms)
Step-by-step explanation:
The chemical formula for water is H²O. The H is the chemical symbol for Hydrogen and O is the chemical symbol for Oxygen. The 2 is a subscript which represents how many atoms of a certain element are in a molecule. In this case, the subscript ² comes after H, indicating that there are two Hydrogen atoms inside water. There is no subscript after O, meaning there is only one Oxygen atom. Therefore, there are two Hydrogen atoms and one Oxygen atom that bond to form water. Hope this helps :))
