Mrs. Best and her friends tried scuba diving for the first time on a cruise to the Bahamas. From the time they jumped off the boat to the time they reached the lowest point, their elevation changed by -24 feet. Which one of these statements could represent their time scuba diving? A. -10 - 42
B. 10 + (-34)
C. 10 + 24
D. -34 + (-10)

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)
