Answer:

Let the integer be called "n"

So we have:

n^2-15=4n-3

n^2=4n+12

n^2-4n-12=0

(n+2)(n-6)=0

So, the negative integer is -2.

What is the value of 10C3?
Zigmanuir [339]
The answer is B. 120

nCr = n! / ((r! * (n - r)!)

n = 10
r = 3

10C3 = 10! / ((3! * (10 - 3)!)
         = 10! / ((3! * 7!)
         = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
         = 3628800 / 30240
         = 120
