The first one is A while the second one is B
5 + 3(2x +4) + 6
5 + 6x + 12 + 6
5 + 12 + 6 +6x
= 23 + 6x
Replace all x's with the value of x.
f(x) = -2x becomes f(3) = -2(3)
f(3) = -2(3)
f(3) = -6
So, -6 is the answer.

Tim said that "<span><em>She drives at a variable speed for 2 minutes, then drives at a constant speed for 4 minutes, and finally stops at the parking area for the next 2 minutes." </em></span>Hope this helps answer your question and have a nice day ahead.
Answer:
3(5x + 3y)
Step-by-step explanation: multiply
3 by 5x and 3y
f(x) is a linear function, so both the domain and the range are the set of real numbers.
