Which of the following is a factor of x³ + 343?
x-7
x² - 14x +49
x² + 7x +49
x+7
Answers
The factor of x³ + 343 is (x + 7).
What is factor ?
A number or other mathematical object is factorized or factored in mathematics by writing it as the product of numerous factors, typically smaller or simpler things of the same kind. One factorization of the polynomial x2 - 4 is 3 5, which is also a factorization of the integer 15.
A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to find factors.
he above algebraic expression needs to be expanded to determine its factor;
Mathematically;
x³ + 343 = (x + 7) (x² - 7x + 49)
Therefore, we can conclude that the factors are (x + 7) (x² - 7x + 49)

Which equation is shown by the model?

Answers
Based on the information we can infer that the equation shown in the image is 1.23 - 0.35 = 0.88 (option B).
How to identify the correct equation?To identify the correct equation we must look at the graph and identify the information it provides. In this case we have two squares divided into 100 squares each. Additionally, the square on the left has 88 squares painted in red and 12 squares with an X inside. In the case of the square on the right, it has 23 squares colored in red with an X inside.
In total we have 123 squares painted in red, which in decimal number is equivalent to 1.23. On the other hand, the number of squares painted red and with an X inside is 35, this value would be 0.35.
On the other hand, the squares painted only in red are 88, so the equivalent in decimal numbers would be 0.88. Therefore, the correct way to express this relationship through an equation would be:

. The faces of a fair cube are numbered1 through 6; the probability of rolling anynumber from 1 through 6 is equally likely. Ifthe cube is rolled 4 times, what is the probabilitythat the number 6 will appear on the top face all4 times?
Answers
Solution:
The probability of an event is expressed as
\(Pr(\text{event)}=\frac{\text{Number of desired outcome}}{Number\text{ of possible outcome}}\)Given a fair cube which has its faces numbered 1 to 6 as [1,2,3,4,5,6].
This implies that the number of possible outcome equals 6.
Given that a 6 will appear when rolled, the probability is thus
\(\begin{gathered} Pr(6)=\frac{\text{Number of }6\text{ in the far cube}}{Number\text{ of possible outcome}}\text{ } \\ =\frac{1}{6} \\ \end{gathered}\)When the cube is rolled four times, the probability thus becomes
\(\begin{gathered} Pr(^{_{}}6)=\frac{1}{6}\times\frac{1}{6}\times\frac{1}{6}\times\frac{1}{6} \\ \Rightarrow Pr(^{_{}}6\text{ four times)=}\frac{1}{1296} \end{gathered}\)Hence, the probability that the number 6 will appear four times is

2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

Comment on the solution
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
Answer:
x=3
Step-by-step explanation:
Write the equation first, 2/3(3x+6)=10
Distribute 2, 2(3x+6)/2
Which equals 6x+12/3=10
Then multiply 3 from both sides 6x+12=30
Subtract 12
6x=18
Divide 6 from both sides

Anna is writing a computer game program. She needs to “move” a square 2 units to the left and 3 down by applying a translation rule to the coordinates of the vertices. The square is aligned with the coordinate axes with one corner of the pre-image square at the origin and the diagonally opposite corner at (4,4). After the transformation what will be the coordinates of the image of each of the four vertices.
A. Write the transformation rule for this particular translation. Use the format given in class.
B. Show the math work that is used to calculate the new coordinates mathematically. State the final coordinate pairs. There should be four pairs of coordinates.
C. Graph, sketch, or draw a picture of the situation. Sketch (on a grid) the pre-image and image of the square. Be sure to include the line segments that form the sides of the square. You MUST label all eight coordinate pairs on your sketch or graph. (You may use Desmos or graph paper for this part. You may even include a link to your Desmos graph.)
Answers
The original square has one verticles at the origin, which is at (0,0), and the opposite corner at (4,4), we draw the square show below:
The transformation is moving each verticles 2 unit left and 3 units down.
In term of x-axis translation (horizontal transformation), we move 2 units left or, -2.In term of y-axis translation ( vertical transformation), we move 3 units down, or -3.The tranformation rulw can be written as:
\(x = x - 2 \\ y = - 3\)
From the graph shown above, we write the 4 cordinate pairs:
(0,0)
(4,0)
(4,4)
(0,4)
Aplying the transformation rule, we subtract 2 from x cordinate and subtract 3 from each y cordinate.
The new transformed cordinate are:
(0,0) >>>>>> (0-2, 0-3) >>>>>>> (-2, -3)
(4,0) >>>>>> (4-2, 0-3) >>>>>>> (2, -3)
(4,4) >>>>>> (4-2, 4-3) >>>>>>> (2, 1)
(0,4) >>>>>> (0-2, 4-3) >>>>>>> (-2, 1)
We name the first four cordinates A,B,C and D, respectively.

Answers
The rate that is equivalent to the rate at which John drove to San Antonio is 60 miles per hour
Which rate is equivalent to the rate at which John drove to San Antonio?From the question, we have the following parameters that can be used in our computation:
John drove from here to San Antonio which is 180 miles away in 3 hours.
This means that
Distance = 180 miles
Time = 3 hours
Using the above as a guide, we have the following:
Speed = Distance/Time
Substitute the known values in the above equation, so, we have the following representation
Speed = 180/3
Evaluate
Speed = 60
Hence. the rate that is equivalent to the rate at which John drove to San Antonio is 60 miles per hour

3^2 - (5 x 2^3)
HELP PLEASE
I need step by step
Answers
Answer:
\(-31\)
Step-by-step explanation:
We need to find the value of: \(3^2 - (5 * 2^3)\).
First we need to look at the BIDMAS rule.
B - Brackets
I - Indices
D - Division
M - Multiplication
A - Addition
S - Subtraction
First we need to work out what is in the brackets which is: \((5 * 2^3)\)
We look at the next rule which is Indices so we do \(2^3\) first.
\(2^3 = 2 * 2 * 2 = 8\)
Then we multiply it by the five which gets us:
\((5 * 8) =40\)
Now that we've finished with what is inside the brackets, we can work out what's outside which is:
\(3^2 = 3 * 3 = 9\).
Now we've simplified it down to:
\(9 - (40)\)
Which gets us:
\(9 - 40 = -31\)
Answer:
-31
Step-by-step explanation:
1. 3^2 - (5 * 2^3)
2. 2*2*2=8
3. 3^2 - (5 * 8)
4. 5*8=40
5. 3^2 - 40
6. 3*3=9

The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
Answers
The statement about probability that is correct would be that the probability of landing on yellow is less than the probability of landing on blue. That is option B.
What is probability?Probability is defined as the total number of possible outcome of an event.
The repeated colour which are numbered from 1 to 8 are as follows:
Sections 1 and 8 are purple. The probability of getting a purple = 2/8 = 1/4Sections 2 and 3 are yellow. The probability of getting a yellow = 2/8 = 1/4 Sections 4, 5, and 6 are blue. The probability of getting a blue = 3/8Section 7 is orange. The probability of getting a orange = 1/8.Therefore, the probability of landing on yellow is less than the probability of landing on blue because 1/4 is less than 3/8.
