Imagine you're an agricultural scientist named Dr. Green working on a project that involves calculating the growth of two different types of crops over time. The growth of Wheat crop is represented by the equation 7x² - 3x, and the growth of Corn crop is represented by 5x² + x + 3. You need to combine these equations to predict the total growth of these crops. What equation represents the total growth?

• 12x² - 2x + 3

• 2x² + 4x + 3

• 12x⁴ + 2x² + 3

• 2x² - 4x - 3

Two engineers are working on a project to optimize a network's data flow. Engineer A improves the network's efficiency with a polynomial improvement of (3x³ + 3x² – 4x + 5), while Engineer B finds another optimization represented by (x³ – 2x² + x – 4). What is the combined improvement to the network's efficiency when both optimizations are applied?

• 4x³ + 1x² – 3x + 1

• 2x³ + 1x² - 5x + 9

• 6x³ + 1x - 1x² - 3

• 3x⁵ +1x - 1x⁵ - 3x
