8x^4 + 2x^2 - 45 = (2x^2 + 5)(4x^2 - 9) = (2x^2 + 5)(2x + 3)(2x - 3)
(a) 2x^2 + 3....no
(b) 2x^2 + 5...yes
(c) 2x - 3....yes
(d) 4x^2 - 9)...no...not when it is fully factored
Can you show all the numbers so I could do the math

What is variable cost ?
Variable costs are expenses that alter as the volume of a good or service a company produces fluctuates. Marginal costs multiplied by the number of units produced make up variable costs. They can be regarded as typical expenses as well. Total cost is divided into two parts: fixed costs and variable costs.
Workers paid = $100
Assuming $1600 is given as a Total cost for the 2000 quantity for chicken and Fixed cost is $800
Total cost = $1600 out of which $800 is the fixed cost
Variable cost = Total cost - Fixed cost
= 1600 - 800
= 800
Numbers of workers hired = Variable cost / Workers pay
Numbers of workers hired = 800 / 100
Numbers of workers hired = 8
Therefore, the number of workers that Ralph hires is 8 workers
