(n+2)^4 =
(n²+4n+4)(n²+4n+4) =
n^4 + 4n³ + 4n² + 4n³ + 16n² + 16n + 4n² + 16n + 16 =
n^4 + 4n³+24n²+ 4n + 16
Hope this helps
Answer:
Opposite angles are the same measure.
Angles around a point = 360°
When you add all the angles, you get 360.
Angle a and b would measure the same and so would angle d and c. So you double the measure for one of those angles and subtract it from 360.
Then, you half that value( divide by 2) and this is to find the measure of the other angle
Given data:
Total number of songs = 8
Rock songs = 3
Reggae songs = 2
Country songs = 3
Probability = Number of favorable outcomes / Total number of outcomes
To find:
When song is selected randomly to play first song and then second song from remaining ones ,
Probability when both the songs are from Reggae songs,


Thus , the probability is 1/28.
