Answer:
The set of solution is {-6,6}
Step-by-step explanation:
That means 2x^2-72=0?
If yes, here the solution for this:
x^2-36=0 (divise both sides by 2)
x^2=36
x^2=6^2
We have x=6 or x= - 6
The set of solution is {-6,6}.
Hope that useful for you.
I believe the answer would be (1) because they are not directly related
Answer: 225km
Step-by-step explanation:
3cm --- 150
