What are the solutions to the equation x2 + 6 x = 40

x=4 or x=-10

Step-by-step explanation:

x² + 6x = 40

x² + 6x - 40 = 40 - 40

x² + 6x - 40 = 0

Use quadratic formula:

a=1 , b=6 , c= -40

x=4 or x=-10

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.
