using the equation where you isolated for r in part a, find the radius of the cylinder. round your answer to the nearest hundredth

Find the multiplicative inverse of 8-12i

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.
