Answer: idk you can figure it out urself
Step-by-step explanation:
This is a round robin style tournament. Given that there are 25 people, and order doesn't matter meaning that the combination AB is equivalent to BA you must use the choose formula.
Thus the answer should be 25C2 or
<em>25! / [(25-2)! * 2!] = 300</em>
If you factor the expression by grouping you should get (3g - 5) (2g +7)
Steps:
1. Factor 11 out of 11g
6g^2 + 11 (g) - 35
2. Rewrite 11 as -10 plus 21
6g^2 + (-10 + 21) g - 35
3. Apply the distributive property
6g^2 + (-10g + 21g) - 35
4. Remove parentheses
6g^2 - 10g + 21g - 35
5. Group the first two and the last two terms
(6g^2 - 10g) + (21g - 35)
6. Factor out the greatest common factor from each group
2g (3g - 5) + 7 (3g - 5)
7. Factor out the greatest common factor, 3g - 5
(3g - 5) (2g + 7)
Therefore the answer is A
Answer:
thats Hard.
Step-by-step explanation:
(n - 2)180 = sum of angles (six sides)
(6 - 2)180 = y
(4) 180 = y
720= y
115+110+x+25+x-30+x+x = 720
4x + 220 = 720
4x = 720 - 220
4x = 500
x = 500/4
x = 125
