-x^2 = -36
Vanyuwa [196]

Answer:

x = ±6

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra II</u>

  • Extraneous solutions and multiple answers/roots

Step-by-step explanation:

<u>Step 1: Define</u>

-x² = -36

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

  1. Divide -1 on both sides:                         x² = 36
  2. Square root both sides:                         x = ±6

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute in -6:                    -(-6)² = -36
  2. Exponents:                           -(36) = -36
  3. Multiply:                                -36 = -36
  1. Substitute in 6:                     -(6)² = -36
  2. Exponents:                           -(36) = -36
  3. Multiply:                                -36 = -36

Here we see that both -6 and 6 do indeed work as solutions.

∴ x = ±6 are both solutions to the equation.

X + y = 7, for x<br><br><br><br><br><br> ....
Anuta_ua [19.1K]

Answer:

x = -y + 7

    or

x = 7 - y

Step-by-step explanation:

x + y = 7

Step 1: Subtract y from both sides to get x alone.

x + y = 7

   -y    -y

x = 7 - y

Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.

A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.
Oksana_A [137]
The diagonal of a square forms two 45-45-90 triangles.

The ratios of the lengths of the sides of a 45-45-90 triangle are

1~:~1~:~\sqrt{2}

The hypotenuse is \sqrt{2} times the length of the legs.

Each leg is the length of the hypotenuse divided by \sqrt{2}.

leg = \dfrac{34}{\sqrt{2}} = 24.0416

perimeter = 4 \times side

perimeter = 4 \times 24.0416

perimeter = 96.166

Answer: he will need 96.2 ft of fencing.
