Step-by-step explanation:
√a is defined only when a >= 0.
Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.
When 4x >= 0, x >= 0.
When x + 2 >= 0, x >= -2.
x >= 0 and x >= -2, therefore we have x >= 0. (D)
Answer:
The answer to your question is: x⁴ + 4x³ + 8x² + 8x - 5
Step-by-step explanation:
(x² + 2x - 1)(x² + 2x + 5) = x⁴ + 2x³ + 5x² + 2x³ + 4x² + 10x - x² - 2x - 5
= x⁴ + 4x³ + 8x² + 8x - 5
the correct answer here would be B. 0.25q + 0.05n

Answer:
The magnitude of a vector is its <u>length</u>.
To calculate the magnitude of a vector in any number of dimensions, square root the sum of the squares of each dimension.
Therefore, if 
then its magnitude is:
Similarly, if 
then its magnitude is:
