The length of segment BD on the triangle is given as follows:
BD = 12.5 units.
How to obtain the length of segment BD?The theorem used to solve this problem is given as follows:
A line parallel to one side of a triangle divides the other two proportionately.
The parallel lines in this problem are given as follows:
BC and DE.
Then the proportional segments are given as follows:
AB and AC.
Thus the proportional relationship that relates these side lengths is given as follows:
(x - 2)/3 = (x + 3)/5.
Applying cross multiplication, the value of x is obtained as follows:
3x + 9 = 5x - 10
2x = 19
x = 19/2
x = 9.5.
Then the length of BD is obtained as follows:
BD = x + 3 = 9.5 + 3 = 12.5.

How to express ratio in simplest form?The United States Department of Transportation Federal Highway Administration said that the average driver traveled 12,724 miles in 2020. That's down from 14,263 average annual miles in 2019. The 2020 average equates to 1,060 miles per month per driver, or about 35 miles per day.Although it's possible, you cannot drive 1000 miles in a day safely with a single driver. This would involve approximately 16 hours of driving before accounting for traffic and rest stops. Assuming a total travel time of 20 hours, you would need to depart in the early hours and share the driving.Often, 100,000 miles is considered a cut-off point for used cars because older vehicles often start requiring more expensive and frequent maintenance when mileage exceeds 100,000.The average American spends 18 days driving per year, with an average of eight hours and 22 minutes per week, a OnePoll study conducted on behalf of Cooper Tire found.Number of miles driven by each person in a week:
Valeria = 7
Taub = 21
Ruby = 35
Number of miles driven by Taub : Number of miles driven by Valeria
= 21 : 7
= 21/7
= 3/1
= 3 : 1
Therefore, the number of miles driven by Taub : number of miles driven by Valeria in a week is 3 : 1 in it's simplest form.

If (z-1/z)=6 find the value of :
(z+1/z)
Answers
So the possible values of (z+1/z) are 6 and 0 for z=5 and z=-1 respectively.
Define Algebric expression.An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.
What is variables and constants ?A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.
We can start by multiplying both sides of the equation by (z+1/z) to get:
(z-1/z)(z+1/z) = 6(z+1/z)
This simplifies to:
z^2 - 1 = 6z + 6
We can then solve for z by isolating it on one side of the equation.
z^2 - 6z - 5 = 0
(z-5)(z+1) = 0
So the solutions to this equation are z = 5 and z = -1
Now we can substitute the value of z back into the original expression to find the value of (z+1/z)
For z = 5, (z+1/z) = (5+1/5) = 6
For z = -1, (z+1/z) = (-1+1/(-1)) = 0
So the possible values of (z+1/z) are 6 and 0.

What is the height of a triangle if its base is 24 cm and its area is 216 cm2?
Answers
The height of a triangle is calculated to be 18 cm if its base is 24 cm and its area is 216 cm².
Given that,
Base = 24 cm
Area = 216 cm²
Height = ?
The formula to find out the area of the triangle is given by,
Area A = 1/2 × Base b × Height h
A = 1/2 × b × h
Making h as subject, we have,
h = (2 A)/b = (2× 216)/24 = 18 cm
Thus, the required height of a triangle is calculated to be 18 cm if its base is 24 cm and its area is 216 cm².

How do you determine the coordinates of a point after a reflection in the y-axis?
Answers
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.
Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).
A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

What are the minimum and maximum values of this?The minimum value of 1/n(x) + 2 over the interval 5≤ x ≤ 8 is 2.This is because 1/n(x) is a decreasing function and the smallest value it can take is 1/n(8) = 1/8. Adding 2 to this gives 2. The maximum value of 1/n(x) + 2 over the interval 5≤ x ≤ 8 is 5.This is because 1/n(x) is an increasing function and the largest value it can take is 1/n(5) = 1/5. Adding 2 to this gives 5. Overall, 1/n(x) + 2 takes on values between 2 and 5 over the interval 5≤ x ≤ 8.This is because 1/n(x) is a decreasing function over the interval and adding 2 to this makes the minimum value 2, while 1/n(x) is an increasing function over the interval and adding 2 to this makes the maximum value 5.The minimum and maximum values for the function 1n(x) +2 over the interval 5≤ x ≤ 8 can be determined by examining the graph of the function over the given interval.Since the function is increasing over the given interval, the minimum value of the function is equal to its value at the lower bound of the interval (x = 5), which is 1n(5) + 2 = 2.71.The maximum value of the function is equal to its value at the upper bound of the interval (x = 8), which is 1n(8) + 2 = 3.11.To learn more about the minimum and maximum values refer to:

Answers
With the help of the given equation, we know that the required slope is (A) 3/8.
What is a slope?In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.
The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.
To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).
So, we have the equation:
-3x + 8y = 12
Calculate the slope as follows:
We need to change it into a more general format.
-3x+8y=12
⇒ 8y = 3x+12
⇒ y = 3x/8+12/8
⇒ y = 3x/8+3/2
If you look at it in terms of y = mx+c, the m would be 3/8.
