Answer:
(3) the polynomial has degree 3. If it were a complex coefficient polynomial, then the answer is 2.
Step-by-step explanation:
I am assuming it is a real coefficient polynomial, otherwise the answer will be 2. Since 3i is a root, then so is its conjugate -3i, therefore the polynomial is a multiple of (x-(-1)) *(x-3i) * (x-(-3i)) = (x+1) * (x²+9), which has real coefficients. Hence, its degree is atleast 3. Option (3) is correct
Answer:
-18
Step-by-step explanation:
So you have to always add the ones with parentheses. I added (-6) + (-6) and I get the answer -12. Last but not least I add -12 + -6 to get -18
This is theoretical.
Empirical is an observation; you saw it happen. Theoretical is a conclusion made without seeing.
It is 4 square cm hopefully that help with part of the question
