Answer:

D

Step-by-step explanation:

The Rational root theorem states that the possible roots ( zeros) of a polynomial are of the form

( plus or minus ) factors of the constant term divided by the factors of the leading coefficient.

For x³ - 3x² + 27x - 8

The factors of constant term (- 8) are ± 1, 2, 4, 8

The coefficient of the leading term x³ is 1

Hence possible zeros are

± (\frac{1,2,4,8}{1}) = ± 1, ± 2, ± 4, ± 8 → D

<u>Algebra I</u>

  • Equality Properties
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

-2(5x - 5.5) + 8 = -9x + 2 - (-5)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute:                              -10x + 11 + 8 = -9x + 2 + 5
  2. Combine like terms:              -10x + 19 = -9x + 7
  3. Add 10x to both sides:          19 = x + 7
  4. Subtract 7 on both sides:     12 = x
  5. Rewrite:                                  x = 12
