Look here. I shall wipe the proverbial floor with your mediocre brain.

nwaanambra1:


ok. my bad. sorry.

CACAWA:
hahhahaha...Take that back bro, I am not on your level.

You have no idea who you are joking with.

√(x ) + √(x+15) = 15

Find x.

AkinPhysicist what is x?

Solution
Using simple logic: Imagine the animals all raise one leg. When this is done, there will be a total of 80 – 28 = 52 legs visible. Then imagine each of the animals raising a second leg, then there will be 52 – 28 = 24 legs left. Since the chickens have only two legs, all the 24 legs must belong to the rabbits. Now since the rabbits have already raised two legs, then each of the rabbits must be contributing 2 legs to the 24. Therefore there are 24 divided 2 = 12 rabbits. Therefore, since there are 28 animals in total, then there are 28 – 12 = 16 chickens.

Format mathematics method:
Let X be the number of Chickens and Y be the number of Rabbits. Here is the formal mathematical approach.
X + Y = 28 (1)
2X + 4Y = 80 (2)

Multiply eq.1 by 4:
4X + 4Y = 112 (3)
Subtract eq.2 from eq. 3:
2X = 112 – 80 => 2X = 32 => X = 16 therefore Y = 28 – 16 = 12.

An average ss2 student will solve this nw

GodIsBiafran:


Don't mind that fool. I was expecting him to come up with something really clever. He comes up with this boring rubbish that anyone can type into mathematica and solve. Sad!

YungMillionaire:


Honestly, that guy fall my hand o! I was expecting something really clever and tricky. He comes up with this plain bread. SMH.

CACAWA:


All of you quoting me, including the "smart guy" who has absconded cannot even drop the answer, yet out claim it's an easy one.

I'm not even here to insult anyone, neither will i feel insulted by the way you talk to me.

We can have some fun challenging ourselves to maths questions... Without throwing abuses.

So can anyone just tell me what x is?

Don't even show your workings...Just tell me what x is

YungMillionaire:


Guy, NL math guys respect cleverness (both in problem and solution). Your problem does not display this trait. Any1 can type this on Matlab and obtain the solution by brute force. It is not obvious that your problem has a clever solution angle.

AKIN PHYSICIST WHERE U AT?

Horllamideh:

Baba nla......mo gbedii fun yin....u sabi

CACAWA:
lol....Matlab you say.

That's why i expected you to drop the answer i. 3 minutes.

I judged wrong.

Well you now have spent 3 hours or so on it..What happened to your Matlab?

Lol. You better sit down and learn.

X = 49


Take √(x) from both sides.

Square both sides

Collect like terms,

That linearises the problem.

Solve for x.

Q.E.D

Now, next question.

Y = arcsin(x+x^2) + arccos(xy)

Find dy/dx

AkinPhysicist:
This mumu spitting all over the thread - Okay put 49 for X and see what happens. I can solved this problem the moment you posted it. But like my colleagues above said, its too boring. You need to be more creative bruh. Here is my Homework for you:

post a solution that DOES NOT involve taking squares of but sides. Shikena.

AkinPhysicist:


I dey kampe - wetin dey shak u 4 body?

AkinPhysicist:

edii ke? ki ni ma fi edii ako she abi abo ni ye ni?

irepnaija4eva:
- Okay put 49 for X and see what happens. I can solved this problem the moment you posted.



@CACAWA NA TRUE?

dchem:
Its simple. 28 of 2 leg is 56 remaing 24 legs which could be used by only 12 rabbit. So we have 12 rabbit and 16 chicken. There you go without formal mathematics.

CACAWA:


Lol, Matlab at last isn't it.

Of course another solution that doesn't involve squaring both sides is the use of ITERATION.

NOW, here is your assignment, post a solution that does not involve numerical, graphical or algebraic analysis. Not also involving the use of geometrical representation.

CACAWA:
lol , the guy was slow.

I have frnds like that, you give them a question and they broadcast it to their more brilliant frnds on Whatsapp.

I had thought he'd drop the answer in 3 minutes
