Question

The absolute value of 4 + Ti is equal to the square root of

a. 16
b. 20
c. 25
d. 65

Answer 1

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.
