A rectangular prism has a length of 2 1/2 yd, a width of 1 1/2 yd, and a height
of 1 1/2 yd. You use cubes with fractional edge
lengths of 1 1/2 to find the volume. How many
cubes are there for each of the length, width,
and height of the prism? What is the volume of
the prism?

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)

i’m sorry but i don’t know sorry
