Describe in words the region of double-struck r3 represented by the equations or inequalities. x2 + z2 ≤ 9 here x2 + z2 ≤ 9 or equivalently x2 + z2 ≤ 3 which describes the set of all points in double-struck r3 whose distance from the -axis is at most 3 . thus, the inequality represents the region consisting of all points on or inside a of radius with axis the -axis.

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)
