Da<br> A<br> Solve the equation 2x^2+3=0
Anika [276]

Answer:

x = ±i(√6 / 2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Solving quadratics

<u>Algebra II</u>

Imaginary root i

  • √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2x² + 3 = 0

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

  1. [Subtraction Property of Equality] Subtract 3 on both sides:                        2x² = -3
  2. [Division Property of Equality] Divide 2 on both sides:                                  x² = -3/2
  3. [Equality Property] Square root both sides:                                                    x = ±√(-3/2)
  4. Simplify:                                                                                                             x = ±i(√6 / 2)

Help if cool | will give brainliest
iogann1982 [59]

Step-by-step explanation:

distance walked by him = 1/ 3 miles

time taken in doing so = 3/ 4 hrs.

speed \: acquired \: by \: him \:   =  \frac{distance}{time}

=  \frac{ \frac{1}{3} }{ \frac{3}{4} }  \\  =   \frac{ 1}{3}  \times  \frac{4}{3}  \\  =  \frac{4}{9}  \:  miles \:  hr^{ - 1}

A ladder is leaning against
Svetradugi [14.3K]

Answer:

25 ft

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

15^2 + 20 ^2 = x^2

225+400= x^2

625 = x^2

Take the square root of each side

sqrt(625) = sqrt(x^2)

25 = x
