Hope it was helpfull

1.000.000.000.000- 542000000=  4599458000000

do you want graphic? solution? there is even a "x"?  and where?

Y=-4
X=2/3

hope it has been helpfull

Hope it was helpfull

\(3/4 : -12\)

\(= 3/4 : -12/1\)

\(=3/4 * -1/12\)

\(=-3/48\)

\(=-1/16\)

\(=-0.0625\)

sorry, i wrote it wrong
Change \( {x+1}^{2} \) For:

\({(x+1)}^{2}\)

1. 

What the statement says:

 \(({n+1}^{2})-{n}^{2} = 2n+1\)

 
Demonstration:

\(({n+1}^{2})-{n}^{2} = ({n}^{2}+2n+1)-{n}^{2}- ={n}^{2}+2n+1 -{n}^{2}- =2n+1\)

Example:

\({6}^{2}-{5}^{2}= 36-25=11\)
 

The sum of these two integers
\(6+5= 11\)
I hope it was helpful

= -0
=(-1)*0         (remember "-" is actually (-1))

=0 /               (for property, any number that is multiplied by 0 is 0)

it´s not possible that cos^2(X)>1...
