Answer:

x = − 1 , 2 √ 3 /3 , and − 2 √ 3 /3

Step-by-step explanation:

3x^3+3x^2-4x-4=0

By factoring, I can get simpler equations to get the roots.

x + 1 = 0, or x = -1

√ 3 x + 2 = 0, or − 2 √ 3 /3

√ 3 x - 2 = 0, or 2 √ 3 /3

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

= (38 / 513) * 100

= 7.4074

= 7.41%
