During a winter storm, the temperature on the top of a mountain changed an average of -2.5o C every hour for 12 hours. At noon the temperature was -5o C. During the same period, the temperature at the bottom of the mountain changed at 1/5 the rate of temperature change on the top of the mountain. What is the hourly rate of change at the bottom of the mountain?

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
