(2x – 4) and ( 5x²-2x+6)

10x³ - 24x² + 20x - 24

Step-by-step explanation:

2x (5x² - 2x + 6) - 4 (5x² - 2x + 6)

10x³ - 4x² + 12x - 20x² + 8x - 24

10x³ - 24x² + 20x - 24

I hope this helps!

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
