{3,4,5, 7,9, 10, 13, 17)

Step-by-step explanation:

A = {4, 7, 10, 13, 17)

B = (3, 5, 7, 9).

U means union or join together

A u B  means  {3,4,5, 7,9, 10, 13, 17)

A u B is { 3 , 4 , 5 , 7 , 9 , 10 , 13 , 17 }

Hope this helps

answer: idk

step-by-step explanation:

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)
