Answer:

<em><u>x</u></em><em><u>=</u></em><em><u>2</u></em><em><u>0</u></em>

Step-by-step explanation:

To solve x/4=5

multiply both side by 4 to get:

x/4 (×4) = 5×4

in L.H.S, multipication and division of '4' will cancel each other!

so we will get

x= 5×4 =20

✌️:)

Answer:

x = -6

x = 2

Step-by-step explanation:

x² + 4 - 12 = 0

= (x + 6)(x - 2)

x + 6 = 0

x = -6

x - 2 = 0

I really need help :(((

Answer:

  1. B solving by factoring
  2. A the quadratic formula

Step-by-step explanation:

<h3>1.</h3>

The "zero product principle" or "zero product rule" tells you a product will be zero if and only if one or more of the factors is zero. This fact is used to solve quadratic equations by factoring.

Factoring the equation y = ax² +bx +c to the form y = a(x -r)(x -s) allows you to immediately identify the solutions of y=0 as x=r and x=s. These are the values of x that make the factors zero, hence making the product zero.

Finding the values of x that satisfy ax² +bx +c = 0 by rearranging it to the form a(x -r)(x -s) = 0 is called "solving by factoring."

<h3>2.</h3>

When the process of "completing the square" is applied to the standard-form quadratic y = ax² +bx +c, the result is a formula for the two solutions to y = 0:

  x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

This quadratic formula tells you the solutions based on the coefficients of the original equation, so <em>does not require rearranging</em> the equation in any way.

Answer:

  20°

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary.
