Solve the operations necessary to calculate the value of X, in the following case: X = a * c + b - 2a

For the following values:

a = 2

b = 4

c = -2

Choose one:

a. X = -12

b. X = 4

c. X = 0

d. X = -8

Step-by-step explanation:

x = 2*(-2)+4-2*2

x = -4 +4 -4

x = -4

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
