50 points!! In cold Climate areas, trucks are used to disperse salt on the roads in order to de-ice the roads, making them safe for
travel. In some cases, cone-shaped sheds, made in three different sizes, are used to store the salt during off-season, or
until the roads need to be de-iced. Use the formula for the volume of a cone to complete the table below. Use 3.14 for
height

and me on so we can figure this out

:)

Step-by-step explanation:

it is x equals 3   plese mark me really need it

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)
