Another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.
What is expansion?In mathematics, every real-world issue may be transformed into an equation, sometimes in the form of a factor, which must then be expanded to get a solution.
Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.
Given,
p(x)=2x⁴ + 3x³ −x one factor is (2x−1)
To find another factor we divide p(x)=2x⁴ + 3x³ −x by (2x−1)
Then we got remainder as 0 and quotient ( x³ + 2x + 1 )
So,
(2x−1) ( x³ + 2x² + x ) = 0
(2x−1) (x) ( x² + 2x + 1) = 0
(2x−1) (x) (x + 1)² = 0
Now the solution to this
(2x−1) = 0 ⇒ x = 1/2
(2x−1) (x) ( x² + 2x + 1) = 0 ⇒ x = 0
And
(x + 1)² = 0 ⇒ x = -1
Hence, another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.

Hello!
75,000 - 10% of 75,000
= 75,000 -(10*75,000)/100
= 75,000 -7,5 => 67,500
67,500 - 10% of 67,500
= 67,500- ( 10*67,500)/100
=67,500 - 6,75 = 60,750
60,750 -10% of 60,750
= 60,750-( 10*60,750)/100
= 60,750 - 6,075 => 54,675
Um monumento na cidade de São Paulo, foi construído seguindo a forma de um tronco de pirâmide de bases quadradas. Seu volume é de 21000 m³ e sua altura é de 30 m. Sabendo que sua base maior tem aresta medindo 40 m, calcule a medida da aresta da sua base menor.
Responda:
15cm
Explicação passo a passo:
Volume de uma pirâmide = Área da Base × Altura / 3
Dado
Volume = 2100m³
Altura da pirâmide = 30m
Vamos obter a área base primeiro, substituindo o valor dado na fórmula.
2100 = B (30) / 3
2100 = 30B / 3
2100 = 10B
10B = 2100
Divida os dois lados por 10
10B / 10 = 2100/10
B = 210cm²
Como a base é um quadrado
área da base quadrada = 210cm²
L² = 210
L = √210
L = 14,49cm
C ≈ 15cm
Portanto, a medida da borda de sua menor base é de aproximadamente 15 cm

Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
121.8° is an exterior angle of the lower triangle , then
∠ 2 + 17.3° = 121.8° ( subtract 17.3° from both sides )
∠ 2 = 104.5°
------------------------------------
∠ 2 is an exterior angle of the upper triangle , then
∠ 1 + 37.1° = 104.5° ( subtract 37.1° from both sides )
∠ 1 = 67.4°

The total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.
Let x be the total number of toy cars in Enola's collection:
69% of x = x - 155
0.69x = x - 155
0.31x = 155
x = 500
Thus, the total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Rachel is building a fence around her yard. She wants to create a square area that will have an area of 150 m. If the fencing has been cut into 1m lengths, how much fencing will Rachel need?
Answer:
Rachel will need 49 meters of fencing.
Step-by-step explanation:
From Geometry we know that area of the square ([tex]A[/tex]), measured in square meters, is represented by the following formula:
[tex]A = l^{2}[/tex] (Eq. 1)
Where [tex]l[/tex] is the side length of the square, measured in meters.
The length of the square is now cleared:
[tex]l = \sqrt{A}[/tex]
If we know that [tex]A = 150\,m^{2}[/tex], then the side length is:
[tex]l =\sqrt{150\,m^{2}}[/tex]
[tex]l \approx 12.247\,m[/tex]
The total amount of fencing is equal to the perimeter of the square ([tex]p[/tex]), measured in meters, that is:
[tex]p = 4\cdot l[/tex] (Eq. 2)
If we know that [tex]l = 12.247\,m[/tex], then the perimeter of the square is:
[tex]p = 4\cdot (12.247\,m)[/tex]
[tex]p = 48.988\,m[/tex]
As fencing is cut into 1-m lengths, we need to round this number up to the nearest integer. That is:
[tex]p = 49\,m[/tex]
Rachel will need 49 meters of fencing.
A square and an equilateral triangle have the same perimeter. Each side of the triangle is 3 inches longer than each side of the square. What is the perimeter of the square?
ASAP I ONLY HAVE 15 MINUTES
Answer:
36 inches
Step-by-step explanation:
Q = length of the sqaure
T = length of the triangle
Equation 1: 4Q = 3T
Equation 2: T = 3+Q;
Then, subsitute T=3+Q into equation 1:
4Q = 3(3+Q)
4Q = 9 + 3Q
Q = 9
-----
Each side of the square is 9 inches, so the perimeter will be 9X4 = 36inches

Solve the following equation by completing the square.
A.
B.
C.
D.
Answer:
x = 2 + sqrt(2) or x = 2 - sqrt(2) thus B. is your answer
Step-by-step explanation:
Solve for x over the real numbers:
4 x^2 - 16 x + 8 = 0
Hint: | Write the quadratic equation in standard form.
Divide both sides by 4:
x^2 - 4 x + 2 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 2 from both sides:
x^2 - 4 x = -2
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Hint: | Factor the left-hand side.
Write the left-hand side as a square:
(x - 2)^2 = 2
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the first equation: Solve for x.
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the second equation: Solve for x.
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)

Step-by-step explanation:
Prove that the difference between a two-digit number and the product of its digits will always be a 2 digit number.
Solution:
Let's take the greatest two-digit number as an example.
=> 99Proving...
99 - (9 x 9) = Two-digit number=> 99 - 81 = Two-digit number=> 18 = Two-digit numberSince the difference between the greatest two-digit number and the product of its digits is a two-digit number, the difference between the other two-digit numbers '10, 11, 12.... 97, 98' and the product of its digits will always be a two-digit number, as the product of its digit is less than the two-digit number.
Hence proved. ✔✔
Step-by-step explanation:
Let the two-digit number is [tex]xy[/tex]
This can be written as:
10x + y, where 1 ≤ x ≤ 9 and 0 ≤ y ≤ 9The difference between the number and product of its digits is:
d = 10x + y - xyRewrite this as below:
d = 10x - xy + y - 10 + 10 =
x(10 - y) - (10 - y) + 10 =
(x - 1)(10 - y) + 10
We see that:
0 ≤ x - 1 ≤ 8 according to the condition given above1 ≤ 10 - y ≤ 10 again according to the condition given aboveThe value of d is then:
0 + 10 ≤ d ≤ 8*10 + 1010 ≤ d ≤ 90Proved
