Answer:

28 and none of the alternatives of answer provided matches with it.

Step-by-step explanation:

Let's solve for p, the equation 2 StartRoot 6 + p EndRoot minus 3 p cubed when p = negative 2, this way:

2 √6 + p - 3p³

Let's substitute p with - 2:

2 √6 + -2  - 3(-2)³

2√4 - 3 (-8)

4 + 24 = 28

According to the information given, the result is 28 and none of the alternatives of answer provided matches with it.
