What is similar triangle?If the respective sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are comparable (or proportion). Triangles that are similar will have the same shape but may not be the exact same size. According to the fundamental principles of triangles, two triangles are said to be congruent if their size and shape are the same, but two triangles are said to be similar if their shape is the same but their sizes differ. The proportions of similar triangles are the same.
Here,
Since these are similar triangle,
ME=EN
MN=ME+EN
MN=2ME
this will be same for all the triangles,
1. 2x-9/2x-2=1/2
2(2x-9)=2x-2
4x-18=2x-2
2x=16
x=8
LN=2x-2
LN=14 units
2. 2x-5/x+14=1/2
2(2x-5)=x+14
4x-10=x+14
3x=24
x=8
IH=2x-5
=11 units
3. (x+14)/(x+19)=1/2
2(x+14)=x+19
2x+28=x+19
x=9

How many shelves will he need to build?
Answers
Single bookcase units with two sides, top and bottom should be no wider than 36 inches without a center support.
How wide should shelves be?For most shelves made from 3/4 inch stock, a practical span is 30 to 36 inches. Shelf depth is determined by the size of the items to be stored, generally within the range of 6 to 24 inches. Shelf depth for a general purpose bookshelf is usually 10 to 12 inches. Landon is building new bookshelves for his book store.Plywood for shelves should be 3/4 inch thick or thicker. Standard sheets of plywood come in 1/4-inch, 3/8-inch, 1/2-inch, 5/8-inch, and 3/4-inch thicknesses. Plywood panels over 3/4 inch in thickness are usually special order products.I cut 1 1/2″ strips of plywood and secured three strips to each shelf, including the top and bottom of the bookshelf. The plywood strips are attached on edge, or on their sides, providing the most rigidity.Plywood is the go-to material used for pantry shelves. It's versatile, available in virtually any species of hardwood, and can easily be cut using any table saw. Plywood is ideal for pantry shelves because its edges can be finished with wood trim or iron-on veneer bandingEach shelf can hold 33 books
There are 1221 mystery books

Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
The given problem can be solved as follows,
The equation of the line is y = −23x + 32.
Then, its slope is given by -23.
Since the parallel lines have the same slope, the slope of the line parallel to y = −23x + 32 is -23.
Now, the equation of the line passing through (4, -7) and parallel to the given line can be written as,
(y + 7)/(x - 4) = -23
=> y + 7 = -23x - 92
=> y = -23x + -99

The segments that could be the image of segment AB after a sequence of reflections, rotations, and/or translations include:
A. Line segment GH
D. Line segment NP
F. Line segment CD
What are the segment?From the information, the coordinates of the point A is (1, 2), the coordinates of the point B is (5, 2)
Therefore, the length of the line AB = 5 - 1 = 4 units
In this case, the transformations are, reflections, rotations, and/or translations which are rigid transformations, such that the length of the image of AB will be the same as the length of AB
Therefore, the possible images of AB are;
PN with coordinates P(5, -2) and N(9, -2) and length 9 - 5 = 4 units
HG with coordinates H(-4, -4) and G(-4, -8) and length -4 - (-8) = -4 + 8 = 4 units

What is the 10th term of the geometric sequence 9, -18, 36,
Answers
Answer:
Step-by-step explanation:
Answer: -4608
========================================================
Explanation:
a = 9 = first term
r = -2 = common ratio
We multiply each term by -2 to generate the next term
The nth term for this geometric sequence is a*(r)^(n-1) which becomes 9(-2)^(n-1)
If you tried plugging in say n = 2, you should find that,
9(-2)^(n-1)
9(-2)^(2-1)
9(-2)^1
9(-2)
-18
So that confirms the second term. I'll let you try the other values of n to confirm it further.
----------------------
From here, you plug in n = 10 to find the tenth term
9(-2)^(n-1)
9(-2)^(10-1)
9(-2)^9
9(-512)

There are a certain number of hens and rabbits in a room. The number of feet of the hens exceeds the number of feet of the rabbits by 12, while the number of heads of the hens exceeds the number of the heads of the rabbits by 28. Then the number of hens and rabbits, respectively, in the room are:
Answers
Answer:
22 rabbits and 50 hens
Step-by-step explanation:
Let H and R stand for the numbers of Hens and Rabbits. Each hen has two feet and each rabbit has four feet. Each only has 1 head.
We can set the quantities of feet and heads:
Hens: 2H feet and 1H heads
Rabbits: 4R feet and 1R heads
We are told that:
1.) "The number of feet of the hens exceeds the number of feet of the rabbits by 12" Rewrite this as an expression:
2H - 4R = 12 [feet]
2) "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28" This is written as:
1H = 1R + 28 [heads]
Since each critter only has one head, this last expression will tell us, quickly, how many more Hens there are, which is 28. But by substituting the first expression (the feet) into the second, we can detrermine the exact number of each animal.
Rearrange 2H - 4R = 12 to isolate one of the variables. I'll choose H:
2H - 4R = 12
2H = 12 + 4R
H = (12 + 4R)/2
H = 6+2R
Now use this definition of H in the second equation:
1H = 1R + 28
1(6+2R) = 1R + 28
6 + 2R = 1R + 28
R = 22 There are 22 rabbits
Use this in the second equation to find the number of hens:
1H = 1R + 28
1H = 22 + 28
H = 50 There are 50 hens.
=================
Check:
1.) "The number of feet of the hens exceeds the number of feet of the rabbits by 12."
Hens have 100 feet total. Rabbits have 88 feet. The hens have 12 more total feet: This checks
2.) "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"
There are 50 heans and 22 rabbits. The number of hen heads exceed the number of rabbit heads by 28. This also checks.

Answer:
Q14 x = 3
Q15 No unique solution
Step-by-step explanation:
Q14
The value of x where the line crosses the x axis is the solution for x
Here we see the line crosses the x axis at x = 3 so solution is x =3
Mathematically,
2x - 3 = 3
2x = 3 + 3 adding 3 to both sides
2x = 6
x = 6/2 = 3
Q15
This is a horizontal line which crosses the y-axis at y = 1
Since this does not cross the x axis but is parallel to it, there is no unique solution for x
Mathematically,
-4x + 2 = -4x + 1
Adding 4x to both sides we get the absurdity that 2 = 1 and that indicates no unique solution for x. Alternatively we can say that x has an infinite number of solutions

An ice cream shop sells a small bowl of ice cream for $2.25 and a large bowl for $3. One day, the shop sold 63 bowls of ice cream and made $159. How many of each size bowl did the shop sell?
Answers
The number of small size and large size bowls of ice cream sold in the shop is 40 and 22 respectively.
How to determine the number of each bowl size sold?let
Number of small bowl = x
Number of large bowl = y
x + y = 63
2.25x + 3y = 159
From (1)
x = 63 - y
Substitute into (2)
2.25x + 3y = 159
2.25(63 - y) + 3y = 159
141.75 - 2.25y + 3y = 159
- 2.25y + 3y = 159 - 141.75
0.75y = 17.25
divide both sides by 0.75
y = 17.25 / 0.75
y = 23
Substitute y = 23 into (1)
x + y = 63
x + 23 = 63
subtract 23 from both sides
x = 63 - 23
x = 40
In conclusion, The ice cream shop sold 40 small size bowls and 23 large size bowls

−3+ |n-2 | >5
Please help!!!!
Answers
Step-by-step explanation: To solve this inequality, we can first isolate the absolute value term on one side of the inequality by subtracting |n-2| from both sides of the inequality. This gives us the inequality -3 + |n-2| > 2. Then, we need to consider two cases: when |n-2| is positive and when |n-2| is negative.
If |n-2| is positive, then we can drop the absolute value bars and rewrite the inequality as -3 + (n-2) > 2. Solving this inequality, we find that n > 7.
If |n-2| is negative, then we must reverse the direction of the inequality because subtracting a negative number is the same as adding a positive number. This gives us the inequality -3 - (n-2) > 2. Solving this inequality, we find that n < -1.
Therefore, the solution to the inequality is the set of all numbers that are greater than 7 or less than -1, which is the interval (-1, 7).

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
let's take the weight of five boys is x
so,
x/5 = 62
x = 310
and let's take the weight of four boys is y.
so,
y/4 = 64
y = 256
let's take the weight of a boy which is removed from them is z
so,
x - z = y
x - y = z
310 - 256 = z
z = 54
