Which product of prime polynomials is equivalent to 3x4 – 81x?
3x(x – 3)(x2 – 3x – 9)
3x(x – 3)(x2 + 3x + 9)
3x(x – 3)(x – 3)(x + 3)
3x(x – 3)(x + 3)(x + 3)
Given:
The expression is
[tex]3x^4-81x[/tex]
To find:
The product of prime polynomials which is equivalent to the given expression.
Solution:
We have,
[tex]3x^4-81x[/tex]
Taking out the common factors, we get
[tex]=3x(x^3-27)[/tex]
It can be written as
[tex]=3x(x^3-3^3)[/tex]
[tex]=3x(x-3)(x^2+3x+3^2)[/tex] [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]
[tex]=3x(x-3)(x^2+3x+3^2)[/tex]
[tex]=3x(x-3)(x^2+3x+9)[/tex]
Therefore, the correct option is B.
Answer:
It's B

What is the slope of a line perpendicular to the line whose equation is 4x−10y=404x−10y=40. Fully simplify your answer.
Answer:
[tex] - \frac{5}{2} [/tex]
Step-by-step explanation:
4x -10y= 40
Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.
10y= 4x -40
Divide both side by 10:
[tex]y = \frac{2}{5} x - 4[/tex]
The product of the gradients of perpendicular lines is -1.
⅖(gradient of line)= -1
Gradient of perpendicular line
[tex] = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} [/tex]
[tex] = - \frac{5}{2} [/tex]

If y varies directly as x and y = 5.5 when x = 11, find x when y = 3.5
help
Answer:
7
Step-by-step explanation:
Let us say that [tex]y_{1}[/tex]= 5.5, [tex]x_{1}[/tex]= 11, and [tex]y_{2}[/tex] = 3.5.
[tex]\frac{y_{2}}{y_{1}} =\frac{x_{2}}{x_{1}}[/tex]
[tex]\frac{3.5}{5.5} =\frac{x_{2}}{11}[/tex]
[tex]\frac{7}{11} =\frac{x_{2}}{11}[/tex]
[tex]x_{2} =7[/tex]

Find the value of y, and then find all angles, pls help quick
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angle.
146° is an exterior angle of the triangle, then
5y + 3 + 4y + 8 = 146
9y + 11 = 146 ( subtract 11 from both sides )
9y = 135 ( divide both sides by 9 )
y = 15
Then
∠ A = 5y + 3 = 5(15) + 3 = 75 + 3 = 78°
∠ B = 4y + 8 = 4(15) + 8 = 60 + 8 = 68°
∠ C = 180° - (78 + 68)° ← sum of angles in triangle = 180°
∠ C = 180° - 146° = 34°

Garth is building a square shaped frame for a mirror. The area of the mirror is 144 square inches. How long is each side of the frame, in inches?
Answer: 12 inches
Step-by-step explanation:
This is a square shaped mirror which means that it takes the shape of a square.
All sides on a square are equal and because the way the find the area of a square is to multiple the Length by the Width, you would be squaring the same number to find the area.
Length of each side = √area
= √144
= 12 inches

Q3.
Simon has x sweets.
Yuen has 2 more sweets than Simon.
Giulia has 3 times as many sweets as Yuen.
Simon, Yuen and Giulia have a total of T sweets.
(a) Write down a formula for T in terms of x.
Give your formula in its simplest form.
Here is your answer!
= x + (x + 2) + 3(x + 2) = T
= (3x + 2) + (3x +6) = T
= 3x + 3x + 2 + 6 = T
= 6x + 8 = T

T = 5x + 8 is the formula for T expressed in terms of x.
What is inequality?A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics. Therefore, an imbalance leads to inequity.
Given, Simon has x sweets. Yuen has 2 more sweets than Simon. Giulia has 3 times as many sweets as Yuen. Simon, Yuen, and Giulia have a total of T sweets.
From the given Data,
Thus, in Total sweets, Simon has = x
Total sweets Yuen have = x + 2
Total sweets Giulia have = 3*(x + 2 )
Since the total sweets all three have is T
Hence, T = x + x +2 + 3(x + 2)
T = x + x + 2 + 3x + 6
T = 5x + 8
Therefore, The formula for T in terms of x is T = 5x + 8

What is the probability of drawing a queen or a heart from a standard deck of 52 cards?
Reminder: the four card families
Pleasee helpppppp!!
Answer:
4/13
Step-by-step explanation:
4 queens and 13 hearts
4/ 52 + 13/52 - 1/52
16/52
4/13
Answer:
Step-by-step explanation:
There are 13 hearts in 52 cards. C From above, P(Queen)=4/52 and P Heart=13/52, the queen of hearts is in both categories so we have to subtract 1/52 so we don't double count.
The width of a rectangle measures (8.1g-6.5)(8.1g−6.5) centimeters, and its length measures (4.7g-9.2)(4.7g−9.2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
P = (25.6g - 31.4)
Step-by-step explanation:
Given that,
The width of a rectangle = (8.1g−6.5) cm
The length of a rectangle, = (4.7g−9.2)
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
Substitute all the values,
P = 2(8.1g−6.5+4.7g−9.2)
= 2(12.8g-15.7)
= 25.6g - 31.4
So, the perimeter of the rectangle is equal to (25.6g - 31.4).
The sum of N terms of an arithmetic sequence with first term as 1 and common difference of 2 is 9801. Calculate the value of N.
Answer:
gngngngngngngngngngng
Answer:
n = 99
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 1 , d = 2 and [tex]S_{n}[/tex] = 9801 , then
[tex]\frac{n}{2}[/tex] [ (2 × 1) + 2(n - 1) ] = 9801 ( multiply both sides by 2 to clear the fraction )
n(2 + 2n - 2) = 19602
n(2n) = 19602
2n² = 19602 ( divide both sides by 2 )
n² = 9801 ( take the square root of both sides )
n = [tex]\sqrt{9801}[/tex] = 99
The number of terms summed is 99

Four points are labeled on the number line. P. Q. R. S. Which point represents the value of the absolute value of negative 1 over 2?
Answer:
See Explanation
Step-by-step explanation:
Incomplete question, as the number line is not attached. However, the solution is as follows:
Let y be the absolute value of -1/2 So:
[tex]y = |-\frac{1}{2}|[/tex]
The absolute sign removes all negation. So:
[tex]y = \frac{1}{2}[/tex]
This means that the point at the label [tex]\frac{1}{2}[/tex] or [tex]0.5[/tex] is the solution to the question.
Take for instance, the attached image has point Q at [tex]\frac{1}{2}[/tex].
Hence, Q is the absolute value of -1/2
