Answer is choice D
The reason why is...
3x^6y^2 + 81y^2 = 3y^2(x^6 + 27)
3x^6y^2 + 81y^2 = 3y^2((x^2)^3 + 3^3)
3x^6y^2 + 81y^2 = 3y^2(x^2 + 3)((x^2)^2 - (x^2)*3 + 3^2)
3x^6y^2 + 81y^2 = 3y^2(x^2 + 3)(x^4 - 3x^2 + 9)
Answer:
it would be 53

The pre tax cost of the four DVDs will be:
4 × 9.99 = 39.96
6.75% tax will amount to 6.75/100 × 39.96 →.0675 × 39.96 = 2.697 or 2.70 rounded off.
Cost of DVDs after tax will be 39.96 + 3.70 = 42.66 $
20% discount will be 20/100 × 42.66 →0.2 × 42.66 = 8.53 $
Cost of DVDs with 20% discount will be 42.66 - 8.53 = 34.13
Rounded off to the nearest cent, the total cost of the order is 34 $ and 10 cents.
Given:
The compound inequality is
To find:
The solution for the given compound inequality in interval notation.
Solution:
We have,
Subtracting 6 from each side, we get
Divide each side by 3.
Here, 1 is not included in the solution set and 3 is included in the solution set.
Therefore, the solution in interval notation is (1,3].
