On a coordinate plane, 2 lines are shown. line a b has points (negative 4, negative 2) and (4, 4). line c d has points (0, negative 3) and (4, 0).
which statement best explains the relationship between lines ab and cd?

they are parallel because their slopes are equal.
they are parallel because their slopes are negative reciprocals.
they are not parallel because their slopes are not equal.
they are not parallel because their slopes are negative reciprocals

step-by-step explanation:

the equivalent expression are always the hardest ones but you look at the gcf also

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)
