Pippa has a box containing N pens. There are only black pens and red pens in the box.
The number of black pens in the box is 3 more than the number of red pens.
Pippa is going to take at random 2 pens from the box.
The probability that she will take a black pen followed by a red pen is
9
35
Find the possible values of N.
Show clear algebraic working.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

50x5=$250

step-by-step explanation:

-2x + 7 = 7

x = 0

i think the length is 12 and the width is 17
