Answer:
2n - 2
Step-by-step explanation:
rewrite without parentheses, pretend there is a 1 between the minus sign and the open parentheses that has to be distributed:
3n - 1(2 + n)
3n - (1)(2) + (-1)(n)
3n - 2 - n
combine 3n and -n to get 2n
2n - 2
Answer:
The polynomial with real coefficients having zeros 2 and 2 - 2i is
x³ - 6x² + 16x - 16 = 0
Step-by-step explanation:
Given that a polynomial has zeros at 2 and 2 - 2i, we want to write this polynomial.
We have
x - 2 = 0
x - (2 - 2i) = 0
=> x - 2 + 2i = 0
Since the polynomial has real coefficients, and 2 - 2i is a zero of the polynomial, the conjugate of 2 - 2i, which is 2 + 2i is also a polynomial.
x - (2 + 2i) = 0
=> x - 2 - 2i = 0
Now,
P(x) = (x - 2)(x - 2 + 2i)(x - 2 - 2i) = 0
= (x - 2)((x - 2)² - (2i)²) = 0
= (x - 2)(x² - 4x + 8) = 0
= x³ - 4x² + 8x - 2x² + 8x - 16 = 0
= x³ - 6x² + 16x - 16 = 0
This is the polynomial required.
What is the first point I cant even see it? but all triangles equal 180 degrees so It's B becuase mg and me are 65 degrees 65+65 equals 130. 130 plus 50 is 180 thus your answer I hope I could help <span>(o^▽^o) <3</span>
Answer:
s=32
Step-by-step explanation:
Divide both sides by -5
s-30=2
Add 30 to both sides
s=32
Answer:C
Step-by-step explanation: Current electricity is caused by flowing negatively charged particles. The negatively charged particles that are responsible for the flow of electricity are called electrons.
The force is equal at all points in the field as the field lines are parallel in a uniform field. So, negatively charged particles will move in the opposite direction to the current.
Hence, the correct answer is "C. It is caused by flowing negatively charged particles."
