Answer:
it would be the second opition
Step-by-step explanation:
Answer would be 7 since 2 is a negative you would subtract it from 9
The decimal with one more tenth than 15.237 . . .
15.237 + 0.1 = 15.337
√(144*x²) = (√144)*(√x²) = 12x
Answer is D.12x.
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
