Answer:
Step-by-step
Let the given number be n>2.
For n even, n2+((n/2)2–1)2=((n/2)2+1)2.
For n odd, n2+((n2–1)/2)2=((n2+1)/2)2

standard form of a pythagorean triplet is 2m, m²+1, m²-1
let us take 2m as 36. so
2m=36, m=36/2
therefore m=18
m²+1 =18²+1 = 324+1 =325
m²-1 =18²-1 = 324-1 =323
therefore 36,325,323 form a pythagorean triplet.
For checking, 36²+323² should be equal to 325²

Describe the graph of y+3x^2 and compare it with the graph of y=x^2
Answer:
y = 3x^2 is compressed by 3.
As y = x^2 is the parent graph, you can see how big a difference 3 makes.
Hope this helps!
(Red: y = 3x^2)
(Blue: y = x^2)
The transformation for the given function is vertical compression or stretch.
The given functions are y=3x² and y=x².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The graph for the given functions can be determined as follows
To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Horizontal Shift: None
Vertical Shift: None
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: Compressed
Therefore, the transformation for the given function is vertical compression or stretch.

Hi can I please get some help please thank you please please I need it WILL MARK AS BRAINLIEST !!!
Answer: D
Step-by-step explanation:
A and C are linear equations therefore we can eliminate them.
We are left betwen C and D.
C.
x²=25
x=5, x=-5
For C, we can eliminate because when you solve for x, you get 2 linear equations. You may see the x² and think it's linear, but when you solve it, you get 2 linear equations.
We are left with D. Even if you graph it and it doesn't look like a parabola or quadratic, it is still a quadratic equaiton. The 1/ makes it split both ways.

Answer:
The height of trapezoid is 7km.
Step-by-step explanation:
Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
Let a = 4km,
Let b = 8km,
Let area = 42km²,
[tex]42 = \frac{1}{2} \times (4 + 8) \times h[/tex]
[tex]42 = \frac{1}{2} \times 12 \times h[/tex]
[tex]42 = 6 \times h[/tex]
[tex]6h = 42[/tex]

Answer:
5/6x = -10
=> 5/6x = -10/1
by cross multiplication

=> 6x = 5 × 1 / -10
=> 6x = 1/-2
=> x = 1/-2 ×6
=> x = 1/-12

6 length is 2 height.
So 10(6+4) length is 10/3 height
Answer:
x = 10/3
Step-by-step explanation:
These two triangles are similar by AA similarity, as they share angle A, and both have right angles.
Not we can set up a ratio:
6/(6+4) = 2/x
6/10 = 2/x
3/5 = 2/x
Multiply both sides by 5x,
3x = 10
Divide both sides by 3:
x = 10/3
