Its 30, i multiplied 6x5 and got 30 so im sure its the answer
B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as
i^2 = -1
First simplify
(x^2+2x+1)-4
x^2+2x-3
Then factor
(x+3)(x-1)=x^2+2x-3
I solved your other quesiton too.
Yea it's good but make sure to check your answers to see if you did anything wrong.
Hello!
We have when NRT is held constant a linear relationship between pressure and volume of a container with an ideal gas. Here we have
P1V1=P2V2 solving for P2 we just divide both sides by V2 and we get
P2=P1V1/V2
Hope this helps. Any questions please just ask! Thanks so much!!
