Answer:
19,600
Step-by-step explanation:
0-49=50 numbers
n=50
r=3
C(n,r)=n!/(r!(n-r)!)
=50!/(47!)(3!)
C(n,r)=C(50,3)
=50!/(3!(50−3)!)
= 19600

Answer: 7x-7</h3>
===========================================
Work Shown:
(6x-2)-(-x+5)
6x-2+x-5
(6x+x)+(-2-5)
7x-7
When distributing the negative, don't forget to apply the negative to every term inside the parenthesis. So that means -x flips to x, while +5 flips to -5.
Answer: (x+8)(x+2) = x^2 + 10x + 16
