Solution:
This problem is a permutation because the order matters here. This means that choosing A as King, B as Knight, C as Bishop and D as Rook results in a different arrangement from B as King, A as Knight, D as Bishop and C as Rook. We would count them both because in the first case A is King, but in the second case A is Knight.
Therefore, the possible number of ways are given below:
Hence there will be 93024 ways 19 members of a chess club fill the offices of King, Knight, Bishop, and Rook.
A
8p + 4
Meaning we could split it and do 2*4*p +4
Just follow PEMDAS
Answer:
the answer is d. 4x²+x-6
Step-by-step explanation:
In order to combine the fractions, they need to have the same denominator.
So, multiply each of their numerators by the denominator they need to be equivalent.
This would look like this:
3x/x+3 --> 3x(x)/x(x+3) ---simplify this as--> 3x²/x(x+3)
x-2/x --> (x-2)(x+3)/x(x+3) ---simplify this as --> x²+x - 6/x(x+3)
3x 3x(x) x-2 (x-2)(x+3)
----- ---> ----- and -------- ---> ---------
x+3 x(x+3) x x(x+3)
now that both fractions have the same denominator, we can add their numerators.
3x² + x²+x-6 = 4x²+x -6
This should now look like this:
4x²+x -6
-------------
x(x+3)
The answer to your equation is 60x (2y+5)
Work is shown below
21x3y·2 – 3x·2y + 75x·<span>4
6</span>·21xy-6xy+6·50x
6x (21y-y+50)
Factor 21y-y+50: 10 (2y+5)
6·10x (2y+5)
= 60x (2y+5)
Let’s say there are 3 clown fish.
The number of starfish is 3 times that number so,
3 times 3
3 x 3 =9
So 9 is your answer!
