Answer:
We know that, a³ - b³ = (a - b)(a² + ab + b²)
Now,
- x³ - 27
- (x)³ - (3)³
- (x - 3)(x² + 3x + 9)
Therefore,
- <u>(x² + 3x + 9)</u> is the other factor.
Answer:
Is a relation and a function.
Step-by-step explanation:
Every set of order pairs represent a relation.
Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case
f(-2) = 3
f(2) = 7
f(7) = -12
f(10) = -15
Therefore the relation is a function as well.
16, first you need to add on the four he lost to the 18 he ended with.
Answer is D. 13 is the average
