f'(x)=20x+23, if that's what you mean. (times and take)

Applying the Law of Sines yields:

\(\dfrac{CA}{\sin B} = \dfrac{CB}{\sin A}\)

After some simplification, 

\(\sin B = \dfrac{CA \cdot \sin A}{CB} = \dfrac{4 \sqrt 2 \sin 45^\circ}{4\sqrt 3}\)

Now you can find the value of sin B, and hence the value of B using inverse trigonometric function.

your question doesn't make any sense, x can be anything

Cross-multiply. You will get: 

\(c(c - 1) = 4(c - 5)\)

Now expand both sides, and move all terms to the left-hand side. You will get a quadratic equation. Then you can solve it with the quadratic formula.

A line has slope 2.  Find the area of the triangle formed by this line and the coordinate axes, if the distance between the origin and the line is 8.

Nevermind i figured it out I had my slope wrong it was y=3x-10

no it is not, also that doesnt even look correct on a graph

I tried it anyway, Definitly not right

The correct answer is y = 3x - 13.

(32 - 4) ÷ 32

28/32 = 7/8 = 0.875

87.5%

Fix ittttt

hey brother the DM is messed up

The above 4 numbers are NOT correct! The following 4 numbers are correct:

n = 25, 142, 311, 649

Therefore, the largest n=649

That is great :)

Thanks Max,

It is really great to have you back here again :)

Hi Kakashi,

I like people to interact with their answerers.

If the answerer gives a partial answer, it may be enough to get the asker thinking in the right direction.

That way, askers get help and still have to think thourgh at least some of the problem for themselves. 

They are more likely to learn that way. 

If they look at the answer, think about it for a while and still want more help they can ask for clarifications.

Or for more help.

That is how I encourage answerers to think.  

I want this to be a teaching/help site.

Not a cheat site.

Most times it is not really necessary to give the final answer. 

Square both sides: \(x\ge9^2\)

\(288 \times {3 \over 8} = \color{brown}\boxed{108}\)

Okay!
