<span>(2 + 5i)(2 + i)
= 4 + 10i + 2i + 5i^2
= 4 + 12i + 5i^2</span>
Answer:
The answer is
B.
Step-by-step explanation:
just multiply 4.5 by 8 and you get 36
First you need the equation y=mx+b
you plug in x and y do find b the y intercept
-5 = -1/2*4 +b
-5 = -2 + b
b = -3
y = -1/2x-3
Answer: C
Step-by-step explanation:
2x+6
Answer: (b)
Step-by-step explanation:
Given



for two complex number, 

Apply the above the property

Also, the absolute value of each complex number must be greater than or equal to zero

Taking the intersection of the above values of x, we get
