Given:


To find:
The expression for f(f(x)).
Solution:
We need to find f(f(x)).
![[\because f(x)=4x-7]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%28x%29%3D4x-7%5D)
![[\because f(x)=4x-7]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%28x%29%3D4x-7%5D)
Using distributive property, we get

Therefore, the expression for f(f(x)) is
.
ANSWER
The number that fills in the blanks is 1
<u>EXPLANATION</u>
Two numbers are relatively prime if they have no common factor greater than 1.
For exam 12 and 17 have no common factor greater than 1.
This is equivalent to saying that the greatest common divisor (GCD) of the two numbers is 1.

This means that
and
are relatively prime.
But
. This means 12 and 16 are not relatively prime or coprime
Answer:
I think the first two are right

Step-by-step explanation:
I think the surface area would be 1,846 but i’m not like completely positive. you just do SA= 2(lw+wh+lh) hope this helps!
