Answer:
x = 0, -4 and -3.
Step-by-step explanation:
The given expression is "3x to the power of 3 + 21x squared + 36x = 0".
We can write this expression as follows :
Taking 3x common.
x = 3
Hence, the solution of the given quadratic equation are x = 0, -4 and -3.
Answer:
3 oatmeal muffins
Step-by-step explanation:
First, subtract the 5 muffins she dropped from the total:
73 - 5
= 68
Then, divide this by 13:
68/13
= 5.23
We need a whole number of muffins in each container, so round this down to 5.
This means that there can be 5 muffins in each of the 13 containers.
Find how many will be leftover:
5(13)
= 65
68 - 65
= 3
So, there will be 3 oatmeal muffins left
Answer:
The proof contains a simple direct proof, wrapped inside the unnecessary logical packaging of a proof by contradiction framework.
Step-by-step explanation:
The proof is rigourous and well written, so we discard the second answer.
This is not a fake proof by contradiction: it does not have any logical fallacies (circular arguments) or additional assumptions, like, for example, the "proof" of "All the horses are the same color". It is factually correct, but it can be rewritten as a direct proof.
A meaningful proof by contradiction depends strongly on the assumption that the statement to prove is false. In this argument, we only this assumption once, thus it is innecessary. Other proofs by contradiction, like the proof of "The square root of 2 is irrational" or Euclid's proof of the infinitude of primes, develop a longer argument based on the new assumption, but this proof doesn't.
To rewrite this without the superfluous framework, erase the parts "Suppose that the statement is false" and "The fact that the statement is true contradicts the assumption that the statement is false. Thus, the assumption that the statement was false must have been false. Thus, the statement is true."
Answer:
3 ≥ x
Step-by-step explanation:
Answer:
not existing
Step-by-step explanation:
lim x goes to 0 is
so not exist
I'm not sure if u mean that or this
