Answer:
10^9 = 1,000,000,000 possibilities
Step-by-step explanation:
Technically, it would be 999,999,999 because nobody can be 000-00-0000, but for the sake of your assignment, it is 1 billion. Hope this helped!
-3
5*(-2 + a) = -25
Use distributive property,
5*(-2) + 5*a = -25
-10 + 5a = -25
Add 10 to both sides
5x = - 25+ 10
5x = -15
Divide both sides by 5
x = -15/5
x = -3
The answer is
T= 5j+s+2
HG = EF
GF = HE
