GIVEN: Suppose that in a certain county
of voters are registered as Democrats,
as Republicans,
as Green party, and the rest are considered Independents. You conduct a poll by calling registered voters in the county at random.

.
voters registered as Democrats 
voters registered as Republicans 
voters registered as Green party

Probability that first call will be to Republican

probability that the first call will be to either a Democrat or a Republican



Hence the probability that the first call will be to either a Democrat or a Republican is 
Well the factors of "72" is→ 1,2,3,4,6,8,9,12,18,24,36,72
To find the factor(s) "72" just write out the muliples that equals 72
Answer:
C. 3x
Step-by-step explanation:
The first two choices give 1 solution each.
The last choice gives an infinite number of solutions.
Choice C. gives no solution.
3x + 9 = 3x
Subtract 3x from both sides.
9 = 0
Since 9 = 0 is false, equation 3x + 9 = 3x has no solution.
