For solving equations of unusual things i got y^2=27/z-x^2 would this also be considered correct?

For the percent example at 11:00. I thought 30% off means multiplying 70 by .30 and same for 20% off from the coupon. But, instead you did 100% - 30% = 70% and multiply 70 by .70, why is that? Can you explain it pls?

During the Domain and Range example, does the +3 change to a negative -3 just because its under the square root sign or because of the negative in front of the square root symbol?
If that negative sign in front of the square root symbol was not there, would it still turn into a -3 or remain positive as it is under the square root symbol?
Thank you
