Answer:
x = -4
Step-by-step explanation:
Divide each side by 3, so x can be isolated:
3x = -12
x = -4
So, the answer is x = -4
So I’m a 5th grader...but I wanted to see if I could help you so...this is how I did it.....first I started with the top, 6-2 which is 4 and then I did 4-4 which is 0 then the answer is....( put 2 on the bottom and 0 on the top. I hope I got it right ;(

Answer:
$719.95
Step-by-step explanation:
To find the purchase total, multiply the price by the percent paid and add the percent of tax.
The store offers a 20% discount. This means you pay 80% of the price. So the discounted price is 0.80(849) = 679.2.
Find the tax to be paid by multiplying 0.06(679.2) = 40.752.
Add the tax for the final total.
679.2 + 40.752 = 719.95
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0
</span><span>
This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
