Step-by-step explanation:
=3^2- 2×3×i + i^2
=9- 6i + i^2
The maximum is 4 days
200:42= 4,76
To find out the surface area of a triangular pyramid you have to do 14 x 24 then divide by 2 which gives you 168 then you'll do 8 times 6.9 then divide by 2 which will give you 27.6 which when you add 168+27.6, you'll get 195.
1 yard = 3 feet
Mulitply 8 × 3 = 24
You have 24 feet of wrapping paper.
Divide 24 by 2 = 12
You can wrap 12 presents.
So first one is not a 75W bulb:
P(not a 75Wbulb)=(4+5)/(4+5+6)=9/15
P(a 75W bulb)=6/(15-1)=6/14
9/15*6/14=9/35
