Answer:
Step-by-step explanation:
cos 225 = -cos 45 = -1/√2.
sin 225 = -sin45 = -1√2.
Answer: The polynomial 3x2 is of one variable with a degree of 2.
The polynomial x2y + 3xy2 + 1 is of two variables a with a degree of 3.
Step-by-step explanation: For this case we have the following polynomials:
3x2
x2y + 3xy2 + 1
We have then:
For 3x2:
Classification: polynomial of one variable:
Degree: 2
For x2y + 3xy2 + 1:
Classification: polynomial of two variables
Degree: 2 + 1 = 3
Yesssssss ittttt isssssss
2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7
7 7
