-5*3+2-7+3*6= -15+3-7+18= -1
Answer: whats the answer???? I need it soo badd :((
Step-by-step explanation:
The answers are:
P(9, 2) = 72
P(5, 5) = 120
P(7, 7) = 5040
These are examples of permutations. The problems are asking us to find the total number of ways an event can happen.
In the first case, P(9, 2), we are asked to find the ways that 2 things can be chosen out of a group of 9.
9 x 8 = 72
P(5, 5) = 5 x 4 x 3 x 2 x 1
P(7, 7) = 7 x 6 x 5 x 4 x 3 x 2 x 1
Answer:
B
Step-by-step explanation:
Answer:
well when you are dividing you can multiply the answer and the second number to get the first number. And when you multiply you can divide the answer to any of the number to get the other number. Hope this helped!
