The answer to the question is a.
|34-9|=25
|25|=25
25=25
Reorder the terms: 6.25 + -5y + y^2 = -14 + 6.25
Combine like terms: -14 + 6.25 = -7.75 6.25 + -5y + y2 = -7.75
Factor a perfect square on the left side: (y + -2.5)(y + -2.5) = -7.75
Can't calculate square root of the right side (negative). The solution to this equation could not be determined.
To answer this you need to do the factorial for 8 which is 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 and you'll get the number of combinations that is<span> 40,320</span> because that's the possible number of combinations.
