Answer: 
Step-by-step explanation:
You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.
Do
. Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

Now do
. Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

Your final step is to do
. Write this -2 next to your other two parts
Multiply -2 by (x - 3) to get:

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:
times
Im not exactly sure what you are asking but 18 + 48 is equivalent and simplified!
Answer:
6) 9 7) 8 8) 7 9) 9
Step-by-step explanation:
The formula for compounded continuously is :

Here the Amount triples , so let us say the new amount A=3P

Cancelling P from both sides we get,

Now here we are given rate is 2.75% or 0.0275,

solving for t we get
t=39.95 years
