Answer:
x² - 64
Step-by-step explanation:
Given
(x + 8)(x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 8) + 8(x - 8) ← distribute both parenthesis
= x² - 8x + 8x - 64 ← collect like terms
= x² - 64
Answer:
Line segment JK
because the order of the letters matter when specifying congruent shapes.
Here is dependence between scores and x-values:
where 
is the mean, 
is standard deviation and i changes from 1 to 2.
1. When i=1, 
then
2. When i=2, 
then
Now solve the system of equations:
Subtract first equation from the second:
Then
Answer: the mean is 62, the standard deviation is 20.

I would use this website. Hope it helps!
(4x^4-1)÷x+1
(256x-1)÷x+1
256-1+1
256
The first step shows the problem
The second step powers 4x 4 times
The third step removes x
The 4th step shows the problem after x is removed.
The 5th step is the answer: 256
