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.
Answer:
H=38
Step-by-step explanation:
The answer is A. -3 and its a negative result cause that's how it is, like for ex, -15/3 = -5 or 15/-3 = -5 is a negative, and w<span>hen two positive numbers are divided, the answer is a positive number 15/3 = 5.</span>
Do you have a protractor? If so, use it and place the center whole, that is located at the bottom, and place it on the dot of the angle. where the arrow hits, is your angle degree. You should be able to identify the angle type.
Answer:
n = 5/2
Step-by-step explanation:
(2n + 4) + 6 = -9 + 4(2n + 1)
2n + 4 + 6 = -9 + 8n + 4
2n + 10 = 8n - 5
15 = 6n
n = 5/2
