Answer: see below
Step-by-step explanation  
Let    2 + a = 11 x
Let    35 - b = 11 y
Where x and y are any unknown integer 
subtract the two equations
- 33 + a + b = 11 (x+y)
a+ b = 11 (x+ y) +33
a+ b = 11 (x+y) + 3 (11)
a+ b = 11(x+ y+3)
Which proves that a+b is a  factor of 11

The population of Ohio will be 10 million in the year 1970
The population growth of Ohio is represented by the function:

P is the population in millions
t is the number of years since 1900
To find the year that the population of Ohio will be 10 million, substitute P = 10 into the function P(t) and solve for t

t = 70 years (to the nearest whole number)
70 years after 1900 will be 1970
Therefore, the population of Ohio will be 10 million in the year 1970
