Answer:
72
Step-by-step explanation:
![f(x) = 4x+8\\g(x) = x + 4\\\\1. f(g(x)) = 4(x+4) + 8\\2. f(g(x)) = 4x + 16 + 8\\3. f(g(x))=4x + 24\\\\4. f(g(12)) = 4(12) + 24\\5. f(g(12)) = 48 + 24 = 72\\](https://tex.z-dn.net/?f=f%28x%29%20%3D%204x%2B8%5C%5Cg%28x%29%20%3D%20x%20%2B%204%5C%5C%5C%5C1.%20f%28g%28x%29%29%20%3D%204%28x%2B4%29%20%2B%208%5C%5C2.%20f%28g%28x%29%29%20%3D%204x%20%2B%2016%20%2B%208%5C%5C3.%20f%28g%28x%29%29%3D4x%20%2B%2024%5C%5C%5C%5C4.%20f%28g%2812%29%29%20%3D%204%2812%29%20%2B%2024%5C%5C5.%20f%28g%2812%29%29%20%3D%2048%20%2B%2024%20%3D%2072%5C%5C)
To do these, you have to place the entire function inside the parent function's variables.
You are inputting the value of the function g(x) into f(x)

![4^{x} = 64](https://tex.z-dn.net/?f=%204%5E%7Bx%7D%20%3D%2064)
By taking <span>logarithmic of base 10
∴ </span><span>
![log 4^{x} = log 64](https://tex.z-dn.net/?f=%20log%204%5E%7Bx%7D%20%3D%20log%2064)
∴ x log 4 = log 64
∴
![x = \frac{log \ 64}{log \ 4}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7Blog%20%5C%2064%7D%7Blog%20%5C%204%7D%20)
note: we don't need to write the base in case of the base =10
∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
Answer:
437.4 meters squared
Step-by-step explanation:
7.2*4.5=32.4=b
3*4.5=13.5=h
b*h=a
32.4*13.5=437.4m^2
