Answer:
1). (x² + 5) and (x + 4)
2). (x²- 3) and (x + 11)
Step-by-step explanation:
We have to determine the factors of the given expression (x³ + 4x² + 5x + 20) by grouping method.
x³ + 4x² + 5x + 20
= x²(x + 4) + 5(x + 4)
= (x² + 5)(x + 4)
Therefore, factors of the given expression are (x² + 5) and (x + 4).
Second expression is (x³ + 11x² - 3x - 33)
Now we will find the factors of this expression by grouping.
x³ + 11x² - 3x - 33
= x²(x + 11) - 3(x + 11)
= (x² - 3)(x + 11)
Therefore, the factors of the given expression are (x² - 3) and (x + 11).

ITS TIMED. I REALLY NEED HELP!!!
Answer:
(4, –1.5)
Step-by-step explanation:
Tim began with 40 comics
Further explanation:
The equation involve linear equation as there is only one object i.e. comic books
So,
Let x be the number of comic books Tim began with
Then after selling half comics Tim will have x/2 comics remaining
Now when he buys 16 more the expression will be:
He has total 36 books, then
Subtracting 16 from both sides
Multiplying 2 on both sides
We can recheck, if he had 40, half of them will be 20 and adding 16 makes them 36.

ANSWER
The equation is used to find out the length of each side of tank is
3,375 = s³
Reason
As given in the question the shape of the tank is cube.
FORMULA
Volume of cube = s³
where s represented the side of a cube.
volume of cube = 3375 cubic feet
put the value in the above equation
we get
3375 = s ³
∛ 3375 = s
Therefore
s = 15 feet
Hence the equation is used to find out the length of the tank is 3,375 = s³
Hence proved
