The first one is 4*8*6=192. 4*10*3=120. 192+120=312. the answer is 312.
the second one is 9x+24. you do this by multiplying the 3 by the parenthesis and then the 2 by its parenthesis then combine variables.
It is arleady in scientific notation, you can write it like that : 3.92400x10^5 or 0.392400x10^6 or 0.392400K (for Kilo = 10^6)
So first, this is point slope form. The first step is to distribute.)

Then add 4 to both sides.

Then add 2x and it becomes
The right answer is Option B: f(4) = 38
Step-by-step explanation:
Given function is;

For finding f(4), we will put x=4 in the given function; therefore
Putting x=4 in given function,

Therefore;
f(4) = 38 in the given function.
The right answer is Option B: f(4) = 38
