The required measure of x and y for the concurrent triangle is 4 and 2 respectively.
In congruent geometry, the shapes that are so identical. can be superimposed on themselves.
here,
Since the triangle is are concurrent triangle,
x + 4 = 4y - - - - (1)
x = y + 2 - - - - (2)
Solving the above system of the equation,
y + 2 + 4 = 4y
6 = 3y
y = 6 / 3
y = 2
Now put this y in equation 2
x = 2 + 2
x = 4
Thus, the required measure of x and y for the concurrent triangle is 4 and 2 respectively.

The width of a rectangle is 7t-7.5 feet and the length is 7.5t+10 feet. Find the perimeter of the rectangle.
The perimeter of the rectangle is 29t + 5
Define Perimeter.
A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
Given,
width = 7t - 7.5
length = 7.5t + 10
we know, the perimeter of the rectangle (p) = 2 ( l + w)
put the value in given formula,
p = 2 * (7.5t + 10 + 7t - 7.5)
p = 2 * ( 14.5t + 2.5)
p = 2 * 14.5t + 2.5 * 2
p = 29t + 5
Hence, the perimeter of the rectangle is 29t + 5

What is circumference?
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were expanded out and straightened out to a line segment, the circumference would be the length of the arc. The curve length around any closed figure is more often referred to as the perimeter. The term "circumference" can also refer to the circle's actual location, which corresponds to a disk's edge. A sphere's circumference is equal to the length of any one of its great circles. The distance around a circle is its circumference, however this cannot be used as a definition if, as in many introductory presentations, distance is defined in terms of straight lines.

Calculate the rise and run to find the slope of each line! Please help me!!!
The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run" (change in y divided by change in x).
slope of the line = -5/4.
How do you find a slope of a line?Choose two points on the line and calculate their coordinates. Determine the difference in y-coordinates between these two points (rise). Determine the difference in x-coordinates between these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run" (change in y divided by change in x).The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It is usually simple to graph a line using y=mx+b.The line pass through the points (-3, 2) and (1, -3)
The formula for finding slope from two points (x₁, y₁) and (x₂, y₂) on a line is m = (y₂ - y₁) / (x₂ - x₁). Here, m = slope of the line
m = -3-2/1 +3 = -5/ 4

How to determine the equation of the polynomial function?The polynomial function is represented on the given graph
From the graph, we can see that:
The curve of the graph crosses the x-axis at the following points
x = -2 and x = 1
This means that the equation of the polynomial function can be calculated as
y = (x - x₁) * (x - x₂)
Where
x₁ = -2 and x₂ = 1
Substitute x₁ = -2 and x₂ = 1 in the equation y = (x - x₁) * (x - x₂)
So, we have
y = (x + 2) * (x - 1)
Open the brackets
y = x² + 2x - x - 2
Evaluate
y = x² + x - 2
Hence, the equation is y = x² + x - 2

use similar triangles to calculate the height h cm of triangale abe
The height of ∆EBA is 24cm in the given question where two triangles are similar.
What are similar triangles?Similar triangles are triangles that have the same shape but differ in size. Similar objects include all equilateral triangles and squares with any side length. In other words, if two triangles are similar, their corresponding angles and sides are congruent and in equal proportion. The " symbol here denotes the similarity of triangles.
We know that in two similar triangles, the ratio of corresponding sides are equal to ratio of their heights.
We have given that ∆DBC ≅ ∆EBA
So,
⇒ (36-h)/h = DC/AE
⇒ (36-h)/h = 10/20
Using cross multiplication
⇒ 20(36-h) = 10h
⇒ 720 - 20h = 10h
⇒ - 20h -10h = -720
⇒ -30h = -720
⇒ 30h = 720
⇒ h = 720/30
⇒ h = 24

Sarah, Leah, Haley, Lindsay, and Kim bought 4 bottles of water to share among themselves. They divided each bottle of water into 5 equal portions. Sarah took 1 portion from each bottle of water. Which equation represents how much of a bottle of water Sarah took?
Sarah has taken 4/5 portion of the available water bottles.
How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, Total number of water bottles bought = 4
Total number of people sharing the bottles = 5
Since each bottle is divided in equal portion, each portion of bottle = 1/5
Also, Sarah took one portion from each of the four bottles, thus
Sarah has portion of water = 4*(1/5) = 4/5
Sarah has taken 4/5 portion of the available water bottles.
