Leticia is studying the stock market for a class. She had to track a stock for 8 days. On the first day of tracking the stock on the Internet, the stock showed a change of -$2.25. On the second day, the stock changed -$1.50. 1. How much did the stock gain value or lose value over those first two days? Explain how you found your answer.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

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)

it would be a on edgenuit y

the diagram below is your final answer
