Hi there! The word "difference" means to subtract. -2 - -6=4. Therefore, it would be the last one.
Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
Answer:
-2, 3
Step-by-step explanation:
If ×=-2 and y=3 then this would make the inequality equal to one another.
Answer:C
Step-by-step explanation:
I am not that sure.. but I think the answer is C.
There are 18 different possible values for N.
Explanation: 180=2x2x3x3x5
Therefore there are 3x3x2 possibilities.
