These three data sets show the number of text messages sent by Jada, Diego, and Lin over 6
days as well as the mean number of text
messages sent by each student per day.

Jada: mean 5
4 4 4 6 6 6

Diego: mean 6

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

1/4 because there is 4 grades.

ok then what happened.

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)
