<span>Let's assume the mat as a right triangle
Taking length of triangle be x
so height = x-21
and hypotenuse= x+6
for right triangle we can apply pythagoras theorem
so (x+6)^2=x^2+(x-21)^2
expanding we get
x^2 + 12 x + 36 = 2 x^2 - 42 x + 441
solving for x we get
x=9,45
But for length to be 9 height will be negative
So the length of mat will be 45 inches</span>
Answer:
The scale factor is 4
Step-by-step explanation:
* Lets talk about dilation
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the
figure does not change.
- The scale factor, measures how much larger or smaller
the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
* In the problem
- The vertex A of the triangle is (-6 , 4) and its image A' is (-24 , 16)
∵ -24 ÷ -6 = 4
∵ 16 ÷ 4 = 4
∴ The scale factor is 4
∵ 4 > 1
∴ The image of the triangle will be larger
* The scale factor is 4

Answer:
16,000
Step-by-step explanation:
11,319 rounded to the nearest thousand is 11,000.
4,895 rounded to the nearest thousand is 5,000.
11,000 + 5,000 is equal to 16,000.
The answer is:
Both have the same number of data points
Both means are between 3 and 4
Westwood has less variability than Middleton
