Answer:
-56
Step-by-step explanation:
You have a negative plus a positive which will give you a negative for the answer. Because you are adding a positive 28 to a negative 84 you get a negative 56.
Answer: The second and the last answer are correct
Step-by-step explanation:
You can build as many numbers as you like: just pick three primes and repeat them as required.
The only caution is that you have to pick large enough primes to make sure that the result is larger than 1000.
Since
, it is enough that the prime repeating three times is larger than 10.
So, for example, we can pick
- 2, not repeating
- 3, repeating twice
- 11, repeating 3 times
The result is

F(x)= x² + 8
When x = 10
f(x) = 10² + 8 = 108
Answer: 108
There is only one real root, at x=-2, so the polynomial describing this parabola has factors of (x+2) with multiplicity 2. The y-intercept tells you the vertical stretch is 1.
The factorization is y = (x +2)².
