Solve the problem.Euler conjectured that the formula n2 - n + 41 would generate prime numbers for whole numbers n. The formula generates prime numbers for n up to 40 and fails at n = 41. Evaluate Euler's formula for n = 42 and determine whether this is a prime number. If it is not a prime number, give its prime factors.

Solve the problem.A truck rental company rents a moving truck one day by charging $29 plus $0.09 per mile. Write a linear equation that relates the cost C, in dollars, of renting the truck to the number x of miles driven. What is the cost of renting the truck if the truck is driven 190 miles?
A. C(x) = 0.09x + 29; $30.71 B. C(x) = 0.09x + 29; $46.10 C. C(x) = 29x + 0.09; $5,510.09 D. C(x) = 0.09x - 29; -$11.90
