X^2=60 what is the value of x ?
olya-2409 [2.1K]

Answer:

x = ±2√15

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Multiple roots/solutions

Step-by-step explanation:

<u>Step 1: Define</u>

x² = 60

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

  1. Square root both sides:                    x = ±√60
  2. Simplify:                                              x = ±2√15

<u>Step 3: Check</u>

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

x = 2√15

  1. Substitute:                    (2√15)² = 60
  2. Evaluate:                       4 · 15 = 60
  3. Multiply:                        60 = 60

x = -2√15

  1. Substitute:                    (-2√15)² = 60
  2. Evaluate:                       4 · 15 = 60
  3. Multiply:                        60 = 60

Here we see that both solutions do indeed work.

∴ x = ±2√15 are both solutions to the equation.

If x varies inversely as y 2, and x = 2 when y = 20, find x when y = 5.
Dominik [7]

Step-by-step explanation:

x =  \frac{k}{y}

x varies inversely as y. This means that x is equal to the inverse of y which can be translated as x = 1/y but the problem said that x is <u>n</u><u>o</u><u>t</u><u> </u><u>e</u><u>x</u><u>a</u><u>c</u><u>t</u><u>l</u><u>y</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>l</u><u> </u>to the inverse of y. Therefore, we need to introduce a factor k. Factor k will represent the word "varies" in the problem.

To illustrate:

x =  \frac{k}{y}

Since we don't have the value of k, we have to solve for it by using the first values of x and y which was given as x=2 and y=20.

x =  \frac{k}{y}  \\ 2 =  \frac{k}{20}  \\ k = 2(20) = 40

Now that we have the value of k, we can now solve for the value of x when y=5.

x =  \frac{k}{y}  \\  =  \frac{40}{5}  \\  = 8

Therefore, when y is 5, the value of x is 8.

Artemon [7]

Answer:

63

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

a² + 9² = 12²

       a² = 12² - 9²

      a² = 144 - 81

     a² = 63

      a = √63
