Let's break down and solve the problems one by one from the image.

1. Problem 1:
   The total cost of (3a - 2b) units of cell phone is (6a² + 5ab - 6b²) pesos. What expression represents the cost of one cell phone?

   To find the cost of one cell phone, divide the total cost by the number of units: $\text{Cost of one cell phone} = \frac{6a^2 + 5ab - 6b^2}{3a - 2b}$

2. Problem 2:
   If one ream of bond paper costs (3x - 4) pesos, how many reams can you buy for (6x⁴ - 17x³ + 24x² - 34x + 24) pesos?

   To find the number of reams, divide the total money by the cost of one ream: $\text{Number of reams} = \frac{6x^4 - 17x^3 + 24x^2 - 34x + 24}{3x - 4}$ Perform polynomial division to get the result.

3. Problem 3:
   If a car covers (15x² + 7x - 2) km in (3x + 2) hours, what is the average speed in km/h?

   Average speed is given by distance divided by time: $\text{Average speed} = \frac{15x^2 + 7x - 2}{3x + 2}$ Perform polynomial division to find the average speed.

4. Problem 4:
   **The volume of a rectangular solid is (x³ + 3x² + 2x - 5) cubic cm, and its height is (x + 1) cm. What is the area
