Which is the best way to solve the equation?

stiks02 [169]

Option D:

Square both sides of the equation is the best way to solve the equation.

Solution:

Given equation:

$\sqrt{x}=k$

To find which is the best way to solve the equation.

Option A: Multiply both sides of the equation by k.

$\sqrt{x}=k$

$k\sqrt{x}=k^2$

In this method, we are not obtain x value.

It is not true.

Option B: Divide both sides of the equation by k.

$$\frac{\sqrt{x}}{k} =\frac{k}{k}$

$$\frac{\sqrt{x}}{k} =1$

In this method, we are not obtain x value.

It is not true.

Option C: Take the square root of both sides of the equation.

$\sqrt{\sqrt{x}}=\sqrt{k}$

$x^{\frac{1}{4} }=\sqrt{k}$

In this method, we are not obtain x value.

It is not true.

Option D: Square both sides of the equation.

$(\sqrt{x})^2=k^2$

Square and square root get canceled.

$x=k^2$

We obtain x value.

It is true.

Therefore square both sides of the equation is the best way to solve the equation.

Option D is the correct answer.

I need to find X, but can't seem to figure it out.

The inside of a trapizoid is always 360 degrees. SO 110+ 130 + x + x-3 = 360

240 + 2x - 3 = 360 236 + 2x = 360 2x = 124 x = 62. I'll leave what the other angle is to you but that is the answer. Hope that helps. if you don't get the steps i took just ask!
