Answer:
B. 40
Step-by-step explanation:
Since we are given the value of x and the expression to evaluate it in, plug in the numeric value of x into the expression and the result is the answer.
Solving:
[tex]\section*{Solving Steps:}4\sqrt{x} = 4 \times \sqrt{x} \\\\1.\text{ Substitute }\( x \) with 100: \[ 4 \sqrt{x} = 4 \sqrt{100} \]2. Calculate \( \sqrt{100} \): \[ \sqrt{100} = 10 \]3. Multiply by 4: \[ 4 \times 10 = \boxed{40} \][/tex]
Therefore, the correct answer is: B. 40
