so, 0 is a whole number

5,0

4,1

3,2

2,3

1,4

0,5

so 6 ways

for the first one, it is 3*5=15

for the second one, it is 3*5*7=105

or even easier, you could just use the pythagorean theorem: AB=sqrt(4^2-2^2)=sqrt12=2sqrt3

yes, but 98.25*3 is much easier, and you can round from 294.75 to 295.

I like the second way better.

x+4x=180. 5x=180. x=36.

Then using knowledge that the number of sides of a regular polygon is equal to 360/exterior angle measure, we see that 360/36=10, so there are 10 sides

oops didn't see the post before that

i think there are 14 ways

cormier is right. the weird absolute value thing is NOT absolute value, it represents the greatest integer less than or equal to x. so yeah, thus x would be 8.75

i believe the 2 players are included in the 7 people, so the answer would be 7

if the 2 players weren't included, then the answer would be 5

which is 29.93 m^2, electrivpavlov
