This is the Number Sense Marathon Continued.
If posts get too cumbersome here, then start a new topic!

So, my [unparseable or potentially dangerous latex formula] are as follows::

[unparseable or potentially dangerous latex formula] The product of the coefficients of [unparseable or potentially dangerous latex formula] = [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] The sum of solutions of [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] Find k, [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] The remainder of [unparseable or potentially dangerous latex formula] (I know that you can use synthetic division but can u do it another way?)

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

I think it is the same case for the other post w/ question [unparseable or potentially dangerous latex formula]...

I plugged a generic equation in my calculator for expansion and this is what I got:

[unparseable or potentially dangerous latex formula] is the formula where n in this case would be 55, and x would be 8.
This expands to:

[unparseable or potentially dangerous latex formula]

If you plug in 55 and 8 you get:

[unparseable or potentially dangerous latex formula]

Thanks for the help though... I was able to figure this kind of problem's solution out finally!

Truncate k to two decimal places. _________________________________ (decimal)

The thing I don't get is this:

My answer was [unparseable or potentially dangerous latex formula]
The Ans. Key was dumb enough to deduct 9 pts away by saying [unparseable or potentially dangerous latex formula]

How do you get the right answer for these types of questions and when do you have to realize that you have to add or subtract [unparseable or potentially dangerous latex formula] ?

[101dalmatians]

How many lines are determined by [unparseable or potentially dangerous latex formula], no [unparseable or potentially dangerous latex formula] of which are collinear ?

What is this supposed to [unparseable or potentially dangerous latex formula] ?

Is there a formula for this question?

OMG! How could I not realize L'hopitals rule on that limit??? I thought of simplification like u know - [unparseable or potentially dangerous latex formula] into [unparseable or potentially dangerous latex formula]...
I was trying to apply that for [unparseable or potentially dangerous latex formula] too....
