q + 20 = p
Since the number p is 20 more than the number q, you would put it in an equation to identify the relationship between these numbers. 20 plus q makes p.
Interval notation: (5, ∞).
Set notation: {x | x > 5}
The set notation is and is read “The set of all x such that is x greater than 5.”

Answer:
c = 2
Step-by-step explanation:
Substitute x = 1 + i into the equation
(1 + i)² - 2(1 + i) + c = 0 ← distribute left side
1 + 2i + i² - 2 - 2i + c = 0 ( note that i² = - 1 )
1 + 2i - 1 - 2 - 2i + c = 0 ← collect like terms on left
- 2 + c = 0 ( add 2 to both sides )
c = 2
