We need a matching complex to 2+3i. The conjugate is 2-3i and the two factors are (x-2-3i)(x-2+3i)=(x²-4x+4+9)=x²-4x+13.
The polynomial is (x-4)(x+8)(x²-4x+13)=(x²+4x-32)(x²-4x+13)=
x⁴-4x³+13x²
+4x³-16x²+ 52x
-32x²+128x-416
x⁴-35x²+180x-416 is the 4th degree polynomial.

Fernando has been saving money to buy an e-book reader. A store has just marked down the price of its readers by 40%. Each reade
murzikaleks [220]

Answer:

Fernado saves $90.

Step-by-step explanation:

40% of $150 ( original price ) = $60

$150 - $60 ( original price - discounted price ) = $90 ( savings )

The question asks about the 40% markdown only, so I'd assume you wouldn't reduce it by $25.

But if you did Fernando would save $115 :

40% of $150 ( original price ) = $60

$60 - $25 ( mail-in rebate ) = $35

$150 - $35 ( original price - discounted price ) = $115 ( savings )

2(n+4)=8−n can someone help me
serious [3.7K]

Answer:

n=0

Step-by-step explanation:

2(n+4)=8

Let's simplify this equation.

2(n+4)=8

Now let's separate.

(2)(n)+(2)(4)=8

2n+8=8

Now we will have to subtract 8 from both sides of the equation.

2n+8-8=8-8

Now we got 2n.

2n=0

Now we will make it into a fraction and divide both sides by 2.

\frac{2n}{2}

\frac{2n}{2} is equal  to \frac{0}{2}

n=0

You finally found your answer!

Hope this helps!
