Answer:
Step-by-step explanation:
2n+5...a couple is two people so you need to multiply the number of couples, n, by 2 to get the total number of dancers. Then add the total number of organizers.
Answer:
1. a= 7, A = 49 degrees
Side A = 7 , Side B = 24, Side C = 25
A= 49 degrees, C = 90 degrees , B=41
2. A= 4, B = 6.9, C=8
A= 22 degrees, B = 68, C= 90
3. A= 7, B = 14.4, C=16
A= 45 , B=45 , C=90
In any case. if the x values (-6) are the same for both points the equation of line would be x = -6
6 divided by 1/4 = 24 + 12 divided by 1/4 = 48, then 48 + 24 = 72
