Answer:
B
Step-by-step explanation:
Given
x² + 14x = 51
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(7)x + 49 = 51 + 49 , that is
(x + 7)² = 100 ( take the square root of both sides )
x + 7 = ± 
= ± 10 ( subtract 7 from both sides )
x = - 7 ± 10
Thus
x = - 7 - 10 = - 17
x = - 7 + 10 = 3
To get the total number of games possible, we will use the combination formula.
Total number of games :
= 45
Total of 45 games in the whole tournament.
Meanwhile, if there would be boy-versus-boy, we will have
The answer is 10.
The fraction for boy-versus-boy game will be
10/45 or 2/9 when simplified.
Answer:
