Answer:

Option B. -4x² - 11x + 13

Step-by-step explanation:

Given polynomials are ( -x² + 9 ) and ( -3x² - 11x + 4 )

We have to add them.

( -x² + 9 ) + -3x² - 11x + 4 )

-x² + 9 - 3x² - 11x + 4

Now we will collect similar terms

( -x² - 3x² ) - 11x + ( 9 + 4 )

-4x² - 11x + 13

Therefore, option B is the answer.

MA_775_DIABLO [31]

Answer:

x = 35

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Geometry</u>

  • Definition of a Line: A line is 180°

Step-by-step explanation:

<u>Step 1: Set up equation</u>

40° + (2x + 30)° + 40° = 180°

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

  1. Combine like terms:                    2x + 110 = 180
  2. Subtract 110 on both sides:         2x = 70
  3. Divide 2 on both sides:               x = 35
