Write out how you found the answer.
ollegr [7]

Step-by-step explanation:

DC = DF + FE + EC = 3 + 14 +6 = 23 in (\because FE = AB)

Area of trapezoid ABCD

=  \frac{1}{2} (AB + CD) \times BE \\  \\  = \frac{1}{2} (14 + 23) \times 8 \\  \\  = 37 \times 4 \\  \\  = 148 \:  {in}^{2}

Solve -3x=2x^2-4 using quadratic formula
frozen [14]

Answer:

x=-2.35078, 0.850781

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Quadratic Formula: x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

Step-by-step explanation:

<u>Step 1: Define equation</u>

-3x = 2x² - 4

<u>Step 2: Rewrite into Standard Form</u>

0 = 2x² + 3x - 4

<u>Step 3: Define variables</u>

a = 2

b = 3

c = -4

<u>Step 4: Find </u><em><u>x</u></em>

  1. Substitute:                    x=\frac{-3\pm\sqrt{3^2-4(2)(-4)} }{2(2)}
  2. Evaluate:                       x=\frac{-3\pm\sqrt{9-4(2)(-4)} }{2(2)}
  3. Multiply:                        x=\frac{-3\pm\sqrt{9+32} }{4}
  4. Add:                              x=\frac{-3\pm\sqrt{41} }{4}
  5. Evaluate:                      x=\frac{-3\pm6.40312}{4}
  6. Evaluate:                      x=-2.35078, 0.850781

And we have our final answer!
