The polynomial (a + b)(a² – ab + b²) is reconstructed as (2x + y)(4y² – 2xy + y²), then the correct option is C.
What is polynomial?
Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Tomas learned that the product of the polynomials (a + b)(a² – ab + b²) was a special pattern that would result in a sum of cubes, a³ + b³.
His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.
Then the polynomial equation will be
(2x + y)(4y² – 2xy + y²)

Saturday's attendance could be : 34,612
Step-by-step explanation:
A baseball stadium holds 42,000 people.
Here '4' is at the ten thousands place.
The number for Saturday's attendance contains a 4 with a value 1/10 the value of the 4 in 42,000.
Means the '4' must be at one place less than ten thousand, that is thousand place.
Hence, out of the given options, 34612 is the only option that has '4' on thousand place.
Therefore, the answer is option B.
1/10th of 40000= 4000.
The number 34,612 the 4 is in the thousandths spot

If we think about it in terms of a graph, you've given us one point
on the graph . . . the point (-9, 3). In order to answer the question,

an infinite number of different lines that can go through one point.

The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k
r=200/5
r=40 roses
40 roses when there are 5 weeds.
Answer:
The Inverse variation says that:
,
then the equation is of the form:
or
Here, r represents the number of roses and w represents the number of weeds.
As per the statement:
The number of roses (r) in a garden increases when the number of weeds (w) decreases.
by definition of inverse variation:
....[1]
From the given table:
take any points
r = 20 and w = 10 then;
Substitute in [1] we have;
Simplify:
k = 200
The equation becomes:
We have to find the number of roses when there are 5 weeds.
⇒w = 5
then;
Divide both sides by 5 we get;
r = 40
Therefore, the number of roses are 40 when there are 5 weeds.
