Answer:no
Step-by-step explanation:
5(3(10)+8)
5(30+8)
5(38)=190
8(10)+8
80+8
88
88≠190 so no

Answer:
the first one
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (10, - 6) and r = 6, hence
(x - 10)² + (y - (- 6))² = 6², that is
(x - 10)² + (y + 6)² = 36
Answer:
ight
Step-by-step explanation:
I'll think bout it.
I may join, but I won't be on that much.
The formula for calculating length is:
![\sqrt{ (x_b-x_a)^{2} + (y_b-y_a)^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%28x_b-x_a%29%5E%7B2%7D%20%2B%20%28y_b-y_a%29%5E%7B2%7D%20%7D%20)
We can also write
![x_a - x_b](https://tex.z-dn.net/?f=%20x_a%20-%20x_b%20)
or
![y_a - y_b](https://tex.z-dn.net/?f=%20y_a%20-%20y_b%20)
Why it does not matter?
Let's assume we have 2 numbers, a and b.
When we perform a subtraction:
![a-b](https://tex.z-dn.net/?f=%20a-b%20)
, we get another number
![c](https://tex.z-dn.net/?f=%20c%20)
When we perform another subtraction:
![b-a](https://tex.z-dn.net/?f=%20b-a%20)
, we get a number
![-c](https://tex.z-dn.net/?f=%20-c%20)
When we raise
![c](https://tex.z-dn.net/?f=%20c%20)
or
![-c](https://tex.z-dn.net/?f=%20-c%20)
to the power of 2, the result is the same,
![c^{2}](https://tex.z-dn.net/?f=%20c%5E%7B2%7D%20)
