So basically what you have to do is
2x + -11 = k
Reorder the terms:
-11 + 2x = k
Solving
-11 + 2x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '11' to each side of the equation.
-11 + 11 + 2x = 11 + k
Combine like terms: -11 + 11 = 0
0 + 2x = 11 + k
2x = 11 + k
Divide each side by '2'.
x = 5.5 + 0.5k
Simplifying
the total tax is 14.71
the total cost is 272.71
Answer:
(6x^2 - 5)(x^2 + 2).
Step-by-step explanation:
6x^4 - 5x^2 + 12x^2 - 10
= 6x^4 + 12x^2 - 5x^2 - 10
= 6x^2(x^ + 2) - 5(x^2 + 2)
(x^2 + 2) is common so we have:
(6x^2 - 5)(x^2 + 2).
