Final answer:
The simplified form of -5 square root of 4 times x raised to 2, with x greater than or equal to 0, is -10x.
Step-by-step explanation:
The question asks to simplify the expression -5 square root of 4 times x raised to 2 given that x is more than or equal to 0.
To simplify this expression, we can take the square root of 4, which is 2, and multiply by the square of x (x²), which is simply x, since x is nonnegative.
This results in -5 * 2 * x, which simplifies to -10x.
