What is the product: (х + 5)(х + 12) = Aх2 + 12х + 52

Bх2 + 17

Cх2 - 60

Dx^2 + 17x + 60

E60x72

The product is

your profit is Double the price that you bought the kits

Step-by-step explanation:

x= cost of kit

you buy it x/2

x/2 + 4.5 (1)

x + x/2 +4.5 (2)

let x = 40

40/2 + 4.5 = 24.5

40 + 40/2 + 4.5 = 64.5

64.5 - 24.5 = 40

so

you buy it in x/2 = 40/2 = 20

and sell it in x = 40

40/20 = 2

your profit is Double the price that you bought the kits

Step-by-step explanation:
