A dfc is equal to bfc and that is a fact
Answer is 49
Formula is b^2-4(ac)
3^2-4(2*-5) while a=2, b=3, c=-5
9-4(2*-5)
9-4(-10)
9+40
49
Hope this helps!
Answer:
use the formula r = square root of (V / (pi x h))
The first one is like 5x5x5x5 which is 625 multiplied by 3x3 which is 9 and together the product will be 5,625.
The second one is 5-4 which is 1-3 which is -2 - 2 = -4 - 1 which is -5 so it’s not it because it’s the opposite of the number we need to find.
The third one is kind of messed up because there’s no such thing as 5.4.3 so sorry I can’t do that one.
The fourth one is 15 because you basically add the numbers up.
And the fifth is not 5. It’s 5.1 so that’s not it either.
So I’m sorry I can’t find the answer but at least I have you some background :/
