$421,369.20 , I just had this question on Apex.
Answer:

Step-by-step explanation:
There are only 2 solutions for none of the rooks can capture any of the other rooks: only if they are laid out in either of the 2 diagonal of the chess board
The number of possible combination for the rock to laid out in 8x8 (64 slots) chess board
possible combination
So the probability is pretty thin

Write all numerators above the least common denominator.
8+3/12
Add the numbers.
Solution 11/12
Answer:
3^x -2x +14
Step-by-step explanation:
I will assume you mean 3^x in the function f(x)
f(x) = 3^x+ 10
g(x) = 2x - 4
(f - g)(x) = 3^x+ 10 - (2x - 4)
Distribute the minus sign
= 3^x+ 10 - 2x + 4
= 3^x -2x +14
Answer: the answer is 11
Step-by-step explanation: to find the value of x, you must find the average of the two bases. So the equation would be 56= 4x+2x-10. Once you simplify that, you get x=11.
