What is the formula for 4p2 p 2 4?

Evaluate 4P2 P 2 4 using the formula nPr = n! (n? r)! P r n = n! ( n - r)!. 4! (4? 2)! 4! ( 4 - 2)! Subtract 2 2 from 4 4. 4! (2)! 4! ( 2)!

What is 4P + 9 - 7p + 2?

Simplify this expression: 4p + 9 + (-7p) + 2 4p + 9 + (-7p) + 2 = 4p + 9 - 7p + 2 = -3p +11 s Log in for more information. Question Asked 3/24/2017 12:24:39 PM Updated 3/24/2017 2:13:14 PM 0 Answers/Comments This answer has been confirmed as correct and helpful.

How do you evaluate 9P 4?

How do you evaluate 9P 4? nP r = n! (n ? r)! so 9P 4 = 9! (9 ? 4)! so 9P 4 = 9! 5! = 9 ×8 ×7 × 6 × 5! (5!)

How do you calculate 20p Rule 4?

You backed a horse at 5/1 (£10 stake) and within that race there was a 4/1 non runner, which would be 20p rule 4. It really is that simple! If you have more than one rule then add up all the rule 4's and use the total in the equation above.
