Step-by-step explanation:
(x²-9)/(x+3)
(x²-3²)/(x+3)
(x+3)(x-3)/(x+3)
x-3
x=-3
-3-3=-6
The answer to this problem is neither. To find this you would just plug in each ordered pair into the equation for the x and y values. Then you would compare if they are equal
Okay, again, ive got this.
So when you are dividing with exponents, you subtract the exponents.
The answer would be 15²
