The answer would be to the right since after you factor the equation out the 9 is positive
The first one and the last one
Answer:

Step-by-step explanation:
The formula for the volume of a cone is:

Given:

48 develop a fault out of the total built which is 2400 therefore
48/2400
If needs to be simplified then 1/50
Guessing that the 3 was suppose to be an exponent.
The answer written in standard form is :
4x^3 + 10x - 4
This is called a cubic trinomial.
