Answer:

Fourth option is the correct answer

$(f - g)(x) = 3 {x}^{2} + 6x - 3$

Step-by-step explanation:

$f(x) = 3{x}^{2} + 7x \\ g(x) = x + 3 \\ \\ (f - g)(x) = f(x) - g(x) \\ = 3{x}^{2} + 7x - (x + 3) \\ = 3{x}^{2} + 7x - x - 3 \\ \purple{ \bold{ (f - g)(x) = 3 {x}^{2} + 6x - 3 }}$

Annika bought a tablet online that was 30% off the regular price of $600. If an 8% sales tax was added to the cost of the comput

BigorU [14]

First, find the price of the table after the sale, so
600 x .3 = 180
600 - 180 = 420
Next, find the sales tax
420 x .08 = 33.6
420 + 33.6 = 453.6
Finally, add the shipping
453.6 + 7.5 = $461.1
