Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.

Can someone help me with this problem? thank you!
abruzzese [7]

Answer:

When 6x - 4 = 8, x = 2.

Step-by-step explanation:

6x - 4 = 8

Add 4 to both sides.

6x = 12

Divide both sides by 6.

x = 2

Proof:

6x - 4 = 8

Substitute variable.

6(2) - 4 = 8

Multiply 6 and 2.

12 - 4 = 8

Subtract 4 from 12.

8 = 8

Work out the area of a circle with a radius 6.2cm, take n/pi to be 3.142 and give your answer to 2 decimal places.
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Area is pi times r squared.  I don't know how to write that on the keyboard.  Take your pi(3.142) times the radius(6.2)squared.  Pemdas tell us to do exponents first, so 6.2 squared is 38.44.  To square a number, just multiply it times itself.  So now, we have pi(3.142) times the squared radius(38.44).  So, 3.142X38.44=

120.778  Second place is seven followed by eight.  Round up.  120.78
