Step-by-step explanation:
Combination will be used here as teams are a group.
So using combination:
<em>No. of combination of 'n' things taken 'r' at a time</em>
<em>=
</em>
here n = 11 ,

11<em>C</em>9 <em>= =
</em>
11<em>C</em>9<em> =</em><em> 55</em>
<em>Which are the possible 9 player starting lineups</em>
Answer:
- 1 - 23i
Step-by-step explanation:
The expression is
(3+i)-(5-7i)(-2+2i)
The answer to your question can be found in the image attached below.
We need to multiply the terms and add them together
(3+i) - [ (5)(-2+2i) +(-7i)(-2+2i) ]
= (3+i) - [ -10 +10i + 14i -14i^2]
= (3+i) - [ -10 +10i + 14i +(14)]
= (3+i) - [ 4 + 24i ]
= (3+i) - 4 - 24i
= - 1 - 23i
