A roasted turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the temperature is 77°F. (a) If the temperature of the turkey is 145°F after half an hour, what is its temperature after 45 min? (Round your answer to the nearest whole number.)

(b) After how many hours will the turkey cool to 100°F? (Round your answer to one decimal place.)

the answer is simply just 6n add the two together as they have an n

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)
