Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
2(3x + 1)(x + 1)
Step-by-step explanation:
Given
6x² + 8x + 2 ← factor out 2 from each term
= 2(3x² + 4x + 1) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × 1 = 3 and sum = 4
The factors are + 3 and + 1
Use these factors to split the x- term
3x² + 3x + x + 1 ( factor the first/second and third/fourth terms )
= 3x(x + 1) + 1(x + 1) ← factor out (x + 1) from each term
= (3x + 1)(x + 1) , then
3x² + 4x + 1 = (3x + 1)(x + 1)
and
6x² + 8x + 2 = 2(3x + 1)(x + 1) ← in factored form

What is the y-intercept of the graph?
Answer:
The y-intercept is the vertical line (population of butterflies)
reflection across x = 4
F(3,-5), C(3,-4), P(5,-4)
Given:
Points F(3,-5), C(3,-4), P(5,-4)The triangle FCP is reflected across the line x = 4.
See the attached with both FCP and F'C'P' triangles shown.
The x-coordinates are 1 unit apart from the x = 4 line, hence the new coordinates are 2 units less or greater than the original one and the y-coordinates remain as is.
Reflected points:
F(3, -5) → F'(5, - 5)C(3, - 4) → C'(5, - 4)P(5, - 4) → P'(3, - 4)Answer:
F' = (5, -5)
C' = (5, -4)
P' = (3, -4)
Step-by-step explanation:
When an object is reflected over a vertical line, the x-value changes but the y-value does not change.
To reflect points across x = 4, determine the distance of the x-value of each of the points to the line of reflection by subtracting 4 from the x-values:
F: 3 - 4 = -1C: 3 - 4 = -1P: 5 - 4 = 1Point F is located 1 unit to the left of the line of reflection. Therefore, the reflection of this point is 1 unit to the right of the line of reflection. So the reflection of point F is 2 units to the right of point F:
F' = (3+2, -5) = (5, -5)As point C has the same x-value as point F, the x-value of its reflection in the line of reflection will be the same as point F:
C' = (3+2, -4) = (5, -4)Finally, point P is located 1 unit to the right of the line of reflection. Therefore, the reflection of this point is 1 unit to the left of the line of reflection. So the reflection of point P is 2 units to the left of point P:
P' = (5-2, -4) = (3, -4)Paula is 10 less than thrice Kaye's age. Two years from now, Paula's age is twice Kaye's present age. How old is Kaye now?

What is the formula to find centre?
The general equation to find centre of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
Centre of the CircleThe location of a moving point on a plane such that its separation from a stationary point on the plane remains constant or fixed is described as a circle. The centre of the circle is the name given to the fixed point
A circle's centre and radius make up its 2D shape. Knowing the circle's centre and radius allows us to draw any circle. The number of radii that a circle can have is unlimited. The intersection of all the radii constitutes the centre of a circle. It is also known as the centre of the circle's diameter.
Center of Circle FormulaThe general equation of a circle is another name for the centre of circle formula. If the radius is r, the center's coordinates are (h,k), and any point on the circle is (x,y), the centre of the circle formula is as follows:
(x - h)2 + (y - k)2 = r2
2 = r2

you select a sample of 30 scores from a population of 1,000 scores. you compute the mode, median, and mean on the sample of 30 scores. you then select another sample of 30 scores from the same population. what measure of central tendency is likely to vary least between your first and second samples
The measure of central tendency that is likely to vary least between the first and second samples of 30 scores is the median.
The median is less affected by outliers and variations in the sample compared to the mean and mode, making it less likely to vary between samples.
The median is a measure of central tendency that represents the middle value of a dataset when it is ordered by value. It is a robust statistic, which means that it is not easily affected by outliers or variations in the sample. This is because the median only looks at the middle value of a dataset, and does not take into account the values of the entire dataset, unlike the mean.
The mode, on the other hand, is the value that appears most frequently in a dataset. It is affected by variations in the sample because it is based on the frequency of values. A different sample of the same population may have a different distribution of values, resulting in a different mode.
The mean is the sum of all the values in a dataset divided by the number of values. It is affected by outliers, as a single large or small value can greatly affect the mean. In small samples, the mean can be affected by small variations in the sample.
In conclusion, since the median is based only on middle value of the sample, it is less affected by variations in the sample and outliers, making it less likely to vary between samples.

What is the area of a rectangle?The area of a rectangle is -
Area = Length x Breadth
A = L x B
Given is the perimeter of a rectangle is 108 ft. Also the length is 24 ft more than the width.

Why must the base of a logarithm be a positive real number not equal to 1?
The base of a logarithm must be a positive real number and not equal to 1 because logarithms are defined as the inverse operation of exponentiation. The base must be a positive real number to be able to raise it to the power of the argument and not equal to 1 to get a meaningful result.
The base of a logarithm represents the number that is being raised to a certain power to produce the argument of the logarithm. If the base of a logarithm is not a positive real number, it is not possible to perform this inverse operation.
For example, if the base of a logarithm is 0, it would mean that the argument of the logarithm is being raised to the power of 0, which is always 1. Therefore, the logarithm would be 0 for any argument, which does not provide any useful information.
The base of a logarithm must be a positive real number and not equal to 1 because it is not possible to raise 1 to any power to produce any value other than 1. Therefore, a logarithm with base 1 is not a meaningful concept.

2 students did not attend the Sports Day.
In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. The numerator and denominator are the two components that make up a fraction.
Given that,
Total number of students in a class = 24
Total number of students chosen for drills = 7/14 = 7/14 *24 = 12
Total number of students chosen for various races = 4/16 = 4/16 *24 = 6
Total number of students chosen for gymnastics= 1/6= 1/6* 24 = 4
Thus, the Total number of students participating in sports day = 12+6+4 = 22
Hence, the Total number of students that did not attend sports day= 24 - 22 = 2
Therefore, 2 students did not attend the Sports Day
Correct question: Out of a class of 24 students, 7/14 of the total students were chosen for drills, 4/16 of the total students were chosen for various races, and 1/6 of the total took part in gymnastics. The rest of them did not attend the Sports Day.
