Answer:
A - -6x4y – 2x3y2 + 9x2y3 – 3xy4 + y5
I just took the test
The difference of the polynomials given is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Given are two polynomials are :
(-2x³y² + 4x²y3³ - 3xy⁴) and (6x⁴y - 5x²y³ - y⁵)
We need to subtract the polynomials and find the difference.
(-2x³y² + 4x²y3³ - 3xy⁴) - (6x⁴y - 5x²y³ - y⁵)
By multiplying the signs into the brackets
= -2x³y² + 4x²y3³ - 3xy⁴ - 6x⁴y + 5x²y³ + y⁵
Grouping the like terms, we get
= -2x³y² + (4x²y3³ + 5x²y³) - 3xy⁴ - 6x⁴y + y⁵
= -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Therefore, the difference between the polynomials is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Answer:
[tex]x^3+3x^2-6x-8[/tex]
Step-by-step explanation:
Unfortunately due to your very vague "question", I do not know for sure if -1, -4, and 2 are X values. But assuming they are...
Just like with quadratics, you can foil to easily identify the X value. But this time we are reversing it, and instead of 2 now we have 3.
To set up your polynomial, it should look something like this:
[tex](x+1)(x+4)(x-2)[/tex]
Now you can FOIL it if it requires you, which I have done for you.
[tex]x^3+3x^2-6x-8[/tex]
The volume of a cube is 64 cubic feet. What are the lengths of the sides of the cube?
Answer:
each side is 10 cubic feet.
Step-by-step explanation:
divide. 64 by how many sides there are, (6), and you get your answer.
The side length of the cube is 4 units if the volume of a cube is 64 cubic feet.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
It is given that:
The volume of the cube is 64 cubic feet
Let V is the volume and a is the side length of the cube.
V = 64 cubic feet
As we know,
The volume of the cube can be fins using the formula as follows:
V = a³
Plug V = 64 in the above formula:
64 = a³
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Taking cube root both side:
∛64 = ∛a³
a = 4 units
Thus, the side length of the cube is 4 units if the volume of a cube is 64 cubic feet.

Answer:
10.) is 6
11.) is also 6
Step-by-step explanation:
10.) is 6
because when you subtract exponents 6-3 you get 3 as the exponent which is equal to the first one
11.) is also 6 because subtract the exponents and you get 4.
also is number 12 r^4 I cannot see it . But I will solve for it as 4.
12.) is 3 . because 4 times 3 is 12.
Colleen already owns 28 hair bands, and additional hair bands are priced at 1 for a dollar.
With $15 to spend on new hair bands, how many total hair bands can Colleen own?
Please help
Answer:
After buying additional hair bands, Colleen can own a total of 43 hair bands.
Step-by-step explanation:
Solving this problem entails of finding out the total number of hair bands Colleen can own, based on the amount she already owns and how many more she purchases. Start by reading the problem carefully to break down the information provided.
We know that Colleen already owns twenty eight hair bands. This is important to remember to include. The problem also states that she has a total of fifteen dollars and each individual hair band is priced at one dollar.
Because the hair bands are only a dollar, Colleen can purchase an additional fifteen hair bands.
Setting up an equation will help us solve. Here is how we could set up the equation:
(amount of hair bands already owned = 28) + (number hair bands bought = 15) = (total number of hair bands owned = x)
28 + 15 = x
The equation is now in place. Solve by adding both terms. This is how you will reach the answer.
28 + 15 = x
43 = x
This means that Colleen will have 43 hair bands in total, after purchasing fifteen hair bands.

were the prices of the other two houses? (SHOW WORKING)
desperate need of helppp
Answer:
Cost of the first house : $480,000
Cost of the second house : $320,000
Step-by-step explanation:
An estate agent has three houses for sale. The prices of the houses were
in the ratio 6:4:3 and the cheapest house was priced at $240 000. What
were the prices of the other two houses? (SHOW WORKING)
The prices of the house has a ratio of
6:4:3
Sum total = 6 + 4 + 3 = 13
Cheapest house = $240,000
The sum total cost of the 3 houses = x
x is calculated as:
= 3/13 × x =$ 240,000
= 3x = $240,000 × 13
x = $240,000 × 13/3
x = $1,040,000
The Cost of the first house =
6/13 × $1,040,000
= $480,000
Cost of the second house
= 4/13 × $1,040,000
=$320,000
Therefore,
Cost of the first house : $480,000
Cost of the second house : $320,000

whats the distance rounded to the nearest tenth between the points (2, -2) and (6,3)
Answer:
The answer is 6.4 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(2, -2) and (6,3)
The distance between them is
[tex]d = \sqrt{ ({2 - 6})^{2} + ({ - 2 - 3})^{2} } \\ = \sqrt{ ({ - 4})^{2} + ({ - 5})^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \: \: \: \: \: \: \: \: \: \: \\ = 6.403124237...[/tex]
