Answer:

-2

Step-by-step explanation:

f(x) = x² +3x

so f(-1) means f(x= -1) so wherever you see a "x" in your equation you put a "-1"

f(-1) = (-1)² +3*(-1) = 1 -3 = -2

Answer:

4,151,347,200

Step-by-step explanation:

To find how many ways the train can be made up we use the permutation formula and the values given.

n = 16

k = 9

$_{n}P_{k}=\dfrac{n!}{(n-k)!}$

$_{16}P_{9}=\dfrac{16!}{(16-9)!}$

$_{16}P_{9}=\dfrac{16!}{7!}$

$_{16}P_{9}=4,151,347,200$

So there will be 4,151,347,200 different ways that the train can be made.
