Mrshape:


Make we created a sperate thread.
For it the wife bring 4 question we bring 4 first to provide accurate answer for all before 30minutes

NaijaOlosho:
Wetin concern sucking dick and maths??

djohnson:
S=[n(2a+(n-1)d]/2
open bracket
S=2an+nd-d/2
cross multiple
2S=2an+nd
factor n out from left hand side
2S=n(2a+d)
divide both side by 2a+d

n=2s/2a+d QED

oya na .. Not even the money alone but the fun too

CONTACTSAMSUNG:


Nice one

I must commend, your brain is too quick....... But truth be told if you actually solved what the op sent as screenshot then you failed it

So it's either the op question wasn't properly written..... On that initial n there was a bracket which was not enclosed

So how you got to your derivation I don't/can't still understand

Amotolongbo:
n² = [2S + d-2a]/d
Or

n = [(2S + d-2a)/d] ^0.5

234GT:
The equation posted by the OP is wrong.
Please find below the correct equation.
Mrshape

dejt4u:
lol.. It's still the same thing.. Come on

Amotolongbo:
n² = [2S + d-2a]/d
Or

n = [(2S + d-2a)/d] ^0.5

CONTACTSAMSUNG:


Nah it's not....... In mathematics, every little object, subject and symbol do count sir

davidtemi:
I mean u VS my wife in mathematics

Yes 10k ready game??
