Which of the following methods would be the easiest to use to solve x2 + 5x – 6 = 0?

EastWind [94]

For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.

Twelve athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be given to the second-place

kykrilka [37]

Answer:

1320

Step-by-step explanation:

We are given that

Total number of athelets are running in race=12

Total number of medals =3

We have to find the total possible number of ways can the 3 medals be distributed.

Total number of ways for choosen gold medal=12

Number of ways for choosen silver medal=11

Number of ways for choosen Bronze medal=10

Total number of possible ways= $12\times 11\times 10=1320$

Hence, total number of possible ways in which 3 medals be distributed=1320
