We can tell if the components on each side of the equation are congruent when you see the equals sign with a squiggly line on top. Name the corresponding sides after that. Two triangles with corresponding sides have matching sides. Congruent triangles will have the same length.
How did you recognize the triangles' matching sides?The same two angle pairs are touched by corresponding sides. When the sides are equivalent, you can multiply each side by the same value to move from one triangle to another. The corresponding sides of the triangles in the similar triangles diagram are the same color.The side a (next to b) must match either v or x, for instance, if one polygon has the sequential sides a, b, c, d, and e and the other has the sequential sides v, w, x, y, and z. (both adjacent to w).If two triangles have sides A,B,C and a,b,c, respectively, and they are similar, then the pair of matching sides are proportionate, meaning that A: a = B: b = C.The relationship between the sides and angles of two congruent triangles is referred to as "corresponding parts of congruent triangles," or cpct.To learn more about Triangles refer to:

Using the figure below, Maggie used the definition of vertical angles to help her solve for x. Since vertical angles are congruent, she set the two given expressions equal to each other. After solving for x, her teacher said she got the wrong value for x. Explain where Maggie made her mistake when solving for x.
Answers
Maggie made a mistake while combining similar terms of x using vertical angles; the result is -3x rather than 3x, hence the right answer is x = 9.
How do vertical angles work?When two lines intersect, vertical angles are two angles that are opposed by the same vertex and are congruent, meaning they have the same measure.
The vertical angles for this issue are as follows:
4x + 2.
7x - 25.
Since they agree, the following equation may be used to determine the variable x:
4x + 2 = 7x - 25.
The following results from shifting all terms with x to the left side of the equality and all terms that are constant to the right side, with the opposite signal:
4x - 7x = -25 - 2
Combining similar phrases yields the following results:
-3x = -27.
Maggie made a mistake here since 4x - 7x = -3x, thus the proper answer is as follows:
3x = 27
x = 27/3
x = 9.

What is meant by polynomial function?In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.
Let the given polynomial function be
F(x)=2x³ - 9x² - 6x + 40, the first potential roots are -2, 4 and 5/2.
Solving for the first root, we divide the given function by x+2 where the result is 2x² - 13x + 40.
Since the given polynomial exists divisible by x+2, therefore the first root exists -2.

in an examination room, seating is available for 34 students, which is 85% of the required seating. how many more seats should be added if all students must be seated?
Answers
6 more seats should be added if all students must be seated.
As per the question statement, in an examination room, seating is available for 34 students, which is 85% of the required seating.
We are required to calculate the number of seats to be added to accommodate the seating of all the candidates.
To solve this question, first let us assume that the total number of candidates appearing for the exam is "x", i.e., the room needs "x" seats to accommodate the seating of all the appearing candidates.
And as per the question statement, 85% of x is 34.
We will need to form a linear equation in one variable "x", based on our above-mentioned assumptions and the conditions mentioned in the question statement, and solving this equation, we will obtain our desired answer, i.e.,
(85% of x) = 34
Or, [{(85/100) * x} = 34]
Or, [x = {34 * (100/85)}]
Or, [x = {2 * (100/5)}]
Or, [x = (2 * 20)]
Or, [x = 40]
That is, the total number of candidates appearing for the exam is 40, and hence, the room needs allover 40 seats to accommodate the seating of all the appearing candidates. Therefore, [(40 - 34) = 6] seats need to be added to accommodate the seating of all the candidates.

Answers
The x and y-intercept of the linear equation 10x - 7y = -8 in an ordered pair form are ( -4/5, 0 ) and ( 0, 8/7 ) respectively.
How to determine the x and y-intercept of the linear equation?The intercept of a line on a graph is simply the point at which it intersects either the x-axis or y-axis.
Given the data in the question;
10x - 7y = -8x-intercept = ?y-intercept = ?To find the x-intercept, substitute in 0 for y and solve for x.
10x - 7y = -8
10x - 7(0) = -8
10x - 0 = -8
10x = -8
Divide both sides by 10
10x/10 = -8/10
x = -8/10
x = -4/5
Therefore, the x-intercept is ( -4/5, 0 ).
To find the y-intercept, substitute in 0 for x and solve for y.
10x - 7y = -8
10(0) - 7y = -8
0 - 7y = -8
-7y = -8
Divide both sides by the coefficient of y
-7y / -7 = -8 / -7
y = -8 / -7
y = 8/7
Therefore, the y-intercept is ( 0, 8/7 ).

What is Area?
Area is a quantity that describes the extent of an area on a plane or curved surface. The area of a planar region or planar region refers to the area of a shape or planar layer, while surface area refers to the area of an open surface or boundary of a three-dimensional object
Set each side perpendicular to the wall x
Parallel to the wall would be 320-2x
the area would be:
A(x) = x (320-2x)
A(x) = 320x-2x ^ 2
It is quadratic with a = -2 and b = 320
The largest area will happen when x = -b / 2a
= -320 / (- 2 * 2)
= 80 feet
so the width will be 80 feet and the length will be:
length = 320-2 * 80

{yly} is a real number}
{yly} is an integer}
{yly ≥ 0}
{yly ≤ 0}
Answers
Answer:
{ y l y ≥ 0 }
Step-by-step explanation:
The absolute value parent function is:
[tex]f(x) =|x|[/tex]
The absolute value of a number means how far the number is from zero on a number line. Therefore, the absolute value of a number is its positive numerical value.
This means that regardless of the value of x, the value of the absolute value parent function (y-value) will always be positive or zero.
The range of a function is the set of all possible output values (y-values).
Therefore, the set notation that describes the range of the parent absolute value function is:
{ y l y ≥ 0 }
