At the end of a snow storm, Ashley saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a
steady rate. Let S represent the depth of snow on Ashley's lawn, in
inches, t hours after the snow stopped falling. The table below has
select values showing the linear relationship between t and S.
Determine the original depth of snow on Ashley's lawn.

the first one, all those points on the line just make a strait line.

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)
