n = 10

Step-by-step explanation:

n is the altitude of the right triangle.

Apply the right triangle altitude theorem/geometric mean theorem to find n.

Which is:

h = √(xy)

Where,

h = n =?

x = 5

y = 20

Plug in the value into the equation

n = √(20*5)

n = √100

n = 10

Step-by-step explanation:

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
