WXYZ to JKLM
JM is equal to 9, ZW is 13.5, JK is 12, and WX is 18.
To obtain the coordinates of the other shape, multiply the original shape by the scale factor
What is the scale factor?
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.
13.5 / 9 = 1.5
9 * 1.5 = 13.5 \s12 * 1.5 = 18
You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)
JKLM ~ WXYZ
So JK ~ WX
So the scale factor = WX / JK
Scale Factor = 18 / 12 = 3 / 2 = 1.5

If the perimeter of RSTU is 72 and RV = 16,
find RT and UV
A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16, RT= 32 and UV ≈ 8.2.
How to find the perimeter calculation?A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16.
Finding R T and U V is our goal.
First, let's assume that the figure RSTU is a rhombus since its perimeter and one-half of a diagonal's length are both provided. RT is the result of adding the segments RV and VT.
RT=RV + VT
We are informed that the RV is sixteen. If RV and VT are congruent, then V T equals 16. So:
R T = 16 + 16 = 32
In order to determine the UV length, we must first determine the RU length. Since a rhombus's sides are the same length, we can divide its perimeter by four to determine
RU= Perimeter/ 4
If we simplify and replace Perimeter with 72, we get:
RU = 72 / 4
RU =18
Since UB is a member of the right triangle RUV created by the intersection of the diagonals, we can now use the Pythagorean theorem to determine its length. So:
U V²+ R V² = RU²
If R V = 16 and R U = 18, we obtain:
U V² + 16 ²= 18²
By way of summary, we have:
U V² + 256 = 324
U V² + 256 − 256 = 324 − 256
√ UV = √ 68
UV = 8.2462
UV ≈ 8.2
Our recommendations are as follows:
RT= 32
UV ≈ 8.2.

How to solve the sides of triangle?
Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them.Two triangles must have the same angles and, as a result, must be congruent if their sides are the same. If two triangles are congruent or not, we may determine this simply by looking at their sides.These two triangles are also equivalent if we know that two sides of one triangle and the angle between them are congruent to two sides and the angle between them of another triangle.ΔABC ~ ΔQRS

how to write the equation of the line with m = –1 and Passes point (4, 5) in Slope –Intercept Form.
Hello,
The slope-intercept form of a linear equation is:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
To write the equation of the line with slope m = -1 that passes through the point (4, 5), you can use the point-slope form of a linear equation, which is:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line and m is the slope of the line. Plugging in the values, we get:
y - 5 = -1(x - 4)
This simplifies to:
y - 5 = -x + 4
Finally, we can rearrange the terms to put the equation in slope-intercept form:
y = -x + 9
This is the equation of the line with slope m = -1 that passes through the point (4, 5).

The coordinates of the centroid of triangle DEF with the vertices (0,4) (6,6), and (2,2) is calculated as: (8/3, 4).
How to Find the Coordinates of the Centroid of a Triangle?The formula for finding the coordinates of the centroid of a triangle is given as:
C(x, y) = [tex]( \frac{(x1+x2+x3)}{3}, ( \frac{(y1+y2+y3)}{3})[/tex].
Given the vertices of triangle DEF as follows:

What is a perimeter?
The perimeter of a two-dimensional shape is the distance around the outside of the shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of a triangle is the sum of the lengths of all three sides.
To reflect a point across the line y=x, we can use the following formula:
(x', y') = (y, x)
Where (x', y') is the reflected point and (x, y) is the original point.
Using this formula, we can find the coordinates of the reflected points A' and B':
A' = (4, 4) -> (4, 4) -> (4, 4)
B' = (5, -1) -> (-1, 5) -> (-1, 5)
Therefore, the image of AB is A'B' with endpoints A'(4, 4) and B'(-1, 5).
To find the perimeter of the figure formed by the segments AB, B'B, and A'B', we can add up the lengths of these three segments. The length of AB can be found using the distance formula:
[tex]AB = \sqrt{((5-4)^2 + (-1-4)^2)}\\\\= \sqrt{(1^2 + (-5)^2)}\\\\= \sqrt{(1 + 25)}\\\\= \sqrt{26}[/tex]
The length of B'B can be found using the same formula:
[tex]B'B = \sqrt{((-1-(-1))^2 + (5-5)^2)}\\\\= \sqrt{(0^2 + 0^2)}\\\\= 0[/tex]
The length of A'B' can also be found using the distance formula:
[tex]A'B' = \sqrt{((-1-4)^2 + (5-4)^2)}\\\\= \sqrt{(-5)^2 + (1)^2}\\\\= \sqrt{25 + 1}\\\\= \sqrt{26}[/tex]
The perimeter of the figure is AB + B'B + A'B' = √26 + 0 + √26 = 2√26. To the nearest tenth, this is 5.0.
Hence, the perimeter of the figure is 5.0.

27 -18 = 9
These are not constant, so the sequence is not an arithmetic sequence.
