Answer: 9675
Step-by-step explanation: u don’t want to know do u
Answer:
So it looks like the given zeros are 2i and -3. We have to work backwards.
x = -3 and x = 2i
For -3, we know that out factored form before would have been x + 3
For 2i, that means we took the square root of negative number because it is imaginary. So that means out factored for x2 + 4
So if we put these together:
(x2 + 4)(x + 3) = x3 + 3x2 + 4x + 12

Step-by-step explanation:
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number z = x + iy, [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i, x = 3, y = 1 (Note y is what number that is attached to i)
[3 + i] = √(3^2 +1^2) = √10 = 3.162
X=9
DBC= 54°
The given angle is 90°, so we can add the other two given equations to equal 90.
7x-9+4x=90
1) Combine like terms
11x-9=90
2) Add 9 to both sides
11x=99
3) Divide 11 on both sides
x=9
Now to find the angle:
7x-9
1) Plug 9 in for x (which is what we just solved for)
7(9)-9
2) multiply
63-9
3) subtract
54
m= 54°
