Answer:
OPTION 4
Step-by-step explanation:
Let the three consecutive numbers be n, (n + 1) and (n + 2).
Note that the largest number of the three is (n + 2) and the smallest is n.
So, according to the given data, the sum of all the three integers is equal to 1 more than twice more than the largest number.
Writing it mathematically, we have:
n + (n + 1) + (n + 2) = 12 + 2(n + 2)
This is OPTION (4) and is the answer,
Answer:
Your answer would be
- 2/25 x^3a^3
Or vice versa with the variables
- 2/25 a^3x^3
TO solve it’s pretty simple if you do it correctly.
So with all the variables in the two multiples, you can find a way to combine them
So ignoring everything else you’d get
a^2x * x^2a
You we can see the difference,
theres a^2 and a
Whilst there is also x^2 and x
Now we can combine them
a^3 x^3
Now we can do the normal multipacation with the fraction
2/5 * - 1/5 which is -2/25
Now combine
ANd you got it :D
Using Descartes' Rule of Signs:
The signs are: - + - + - +
There are 5 signs changes in this sequence, so there could be either 5, 3, or 1 positive roots.
If we negate the terms with odd numbers (x^5, x^3), we end up with the signs: - - - - - +
Since there is 1 sign change, there can be only 1 negative root.
This means the positive and negative roots can either be 6, 4, or 2.
Since the total number of roots cannot exceed 6, there are either 0, 2, or 4 complex roots.
