which pair of expressions is equivalent using the associative property of multiplication?

a.6(4a ⋅ 2) = 24a ⋅ 12
b.6(4a ⋅ 2) = (4a ⋅ 2) ⋅ 6
c.6(4a ⋅ 2) = 6 ⋅ 4a ⋅ 2
d.6(4a ⋅ 2) = (6 ⋅ 4a) ⋅ 2

if you need just tell me and i will come to the rescue.

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)

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
