I demonstrate how to calculate the number of square tiles needed for pattern number six, which is 36, and the number of circular tiles for pattern number 20, which is 80. I also explain how to find the fixed charge for deliveries and calculate the difference in costs for two deliveries. Additionally, I cover expanding and factorizing expressions, solving equations, and working with substitution in formulas. Please review the examples and practice similar problems to reinforce your understanding.
