Final answer:
The absolute value of 4 + Ti is equal to the square root of 20.
Step-by-step explanation:
The absolute value of 4 + Ti is equal to the square root of 20.
To find this, we can rewrite the expression as:
|4 + Ti| = √20
Since the absolute value of a real number is always positive, the equation can be simplified to:
4 + Ti = √20
Now, we can solve for Ti by subtracting 4 from both sides:
Ti = √20 - 4
This simplifies to:
Ti = 2√5 - 4
Hence, the correct answer corresponds to b) 20, showcasing the process of manipulating absolute value equations to find the complex expression satisfying the given condition.
