Answer:
19958400 ways
Step-by-step explanation:
As the question involves arrangement, permutation will be used.
P(n,r) = n! / (n-r)!
Here
n=12
and
r = 8
So,
P(12,8) = 12!/(12-8)!
= 12!/ 4!
=19958400 ways
Therefore, the 8 objects from 12 can be arranged in 19958400 ways ..
X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
