The length of the given rectangle is x + 5 meters.
What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal.Given:
Area of rectangle = x² + 8x + 15 sq.metersWidth = x + 3 metersTo find: Length of the rectangle
Finding:
Let 'a' be the length of the rectangle.
We know that area of a rectangle = length * width
On substituting the given values in the above formula, we get:
=> x² + 8x + 15 = a (x + 3)
=> a = [tex]\frac{x^2+8x + 15}{x+3}[/tex]
=> a = [tex]\frac{(x+5)(x+3)}{x+3}[/tex]
=> a = x + 5
Hence, The length of the given rectangle is x + 5 meters.

prove that if all of the 2n subsets of a set containing 2n 1 are equal, then all elements of set n are equal
when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).
Take the power set. It has 2^(2n+1) members.
Replace any member which has n+1 or more elements with its complements.
Now the power set has members, which have n or fewer elements, and each such member appears twice.
Therefore, when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).

Rearrange the formula d=rt to solve for time.
im having a lil trouble with this one guys
Answer:
t = d/r
Step-by-step explanation:
d = rt
We are solving for t, so you need t alone on the left side.
Switch sides.
rt = d
t is being multiplied by r, so you need to divide the left side by r to get rid of r. You must do the same operation to both sides of an equation, so divide both sides of the equation by r.
rt/r = d/r
rt/r is simply t, so we get:
t = d/r

Write an equation to determine the number of points (c) Carlos scored in the last game.
Find the number of points Carlos scored in the last game.
Considering the definition of an equation and the way to solve it, the number of points Carlos scored in the last game is 19.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseBeing:
"C" the number of points Carlos scored."F" the number of points Fabio scored.and knowing that in the last game, Fabio had 7 points less than 2 times as many points as Carlos, the equation to determine the number of points Carlos scored in the last game is:
2C - 7= F
Fabio scored 31 points in the game. So you get:
2C - 7= 31
Solving:
2C= 31 + 7
2C= 38
C= 38 ÷ 2
C=19
Finally, the number of points Carlos scored in the last game is 19.

If f (x) = 3x^4+5, then what is the remainder when f (x) is divided by x+4?
The remainder when polynomial function is divide by linear function is 773.
Given that the polynomial functon f(x)=3x⁴+5 and the linear function is x+4.
As it is given that we have to find the remainder the polynomial
f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4.
f(x)=3x⁴+5 .......(1)
g(x)=x+4 .......(2)
We know the remainder theorem that when a polynomial f(x) is divided by a linear expression (x−a), the remainder will be f(a).
From equation (2), we have a linear expression.
Now, on simplifying equation (2) to obtain the zero of g(x), we get
g(x)=x+4=0
x+4=0
Now, on comparing (x+4) and (x−a), we get
a=-4 ......(3)
Here, we have to get the value of f(a).
Now, using the remainder theorem, we can say that to get the remainder when the polynomial f(x)=3x⁴+5 is divided by g(x)=x+4, we have to replace x by -4 in the polynomial f(x)=3x⁴+5, we get
f(-4)=3(-4)⁴+5
f(-4)=3(256)+5
f(-4)=768+5
f(-4)=773
Therefore, the remainder when the polynomial f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4 is 773.

Which weight represents the 65th percentile?
The 65-th percentile is approximately 83.8 ounces.
A number at or below which a particular percentage falls in its frequency distribution, or a score below which a given percentage falls, is known as the k-th percentile in statistics. The 50th percentile, for instance, is the score at or below which 50% of the distribution's scores can be found.
The 50-th percentile is called the median.The 25th and 75th percentile is called the lower and upper percentile respectively.Mean of a data-set is the measure of central tendency which denotes the average of the data.The standard deviation denotes the fluctuations of the data from the central tendency.The percentile can be calculated by using the formula
Percentile Value = μ + zσ where
z is the z-score , μ is the mean and σ is the standard deviation.
Here the percentile that is to be calculated is 65.
So we take the value that is closest to 0.65 from the z-table.
We get the value of the data to be 0.39
Now putting the values in the equation we get:
Percentile Value = μ + zσ
or, Percentile Value = 83 + (0.39 × 2)
or, Percentile Value = 83.78
or, Percentile Value ≈ 83.8
Hence the 65th percentile value of the function is given by 83.8 .

The domain of a function is the input values that the function can take. The range is the set of values that can be the possible output of the function. The domain of a graph are the values that are on the x-axis and the range is on the y-axis. The arrow means that the graph goes on till infinity, a solid sphere means that the graph ends at that point and the ending point is included in the function, a hollow sphere means the graph ends at that point and the ending point is not included in the function. In the graph in the question, along x-axis the values on left goes on till negative infinity and on right the domain is open at 5. For range along y-axis, the range on the left side goes on till negative infinity and on the right it is open at 2.

The length and the widths are 420.031 yards and 0.031 yards if a rectangular parking lot has a length that is 420 yards greater than the width.
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let L be the length and W be the width of the rectangle.
From the question:
L = 420 + W (based on the data given in the question)
LW = 13
(420 + W)W = 13
W² + 420W - 13 = 0
After solving the above quadratic equation:
W = 0.031, W = -420.03 (width cannot be negative)
W = 0.031 yards (which is not practical but from a mathematical point of view it can be considered)
L = 420 + 0.031 = 420.031 yards
Thus, the length and the widths are 420.031 yards and 0.031 yards if a rectangular parking lot has a length that is 420 yards greater than the width.
