The result is
9
a
2
−
16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−
b
)
=
a
2
−
b
2
.
By applying this to our question, we obtain that:
(
3
a
−
4
)
⋅
(
3
a
+
4
)
=
(
3

)
2
−
(

Answer:
you have to do the math for each one to get the answer i dont know sorry bro
Step-by-step explanation:
Answer: -16
Step-by-step explanation:
f(g(x)) = 2(4(-2)) + 5
f(g(x)) = 2(-8) + 5
f(g(x)) = -16 + 5
f(g(x)) = -11
f(0) = 2(0) + 5
f(0) = 5
f(g(x)) - f(0) = -11 - 5
f(g(x)) - f(0) = -16
It would be 1008 people because all you would do is 114 times 7 and that would be the answer. Why? Because you need to take the amount of people per train and multiply that by the amount of cars. Hope this helped comment if it did!
