Solution, solve\:for\:x,\:\left|x\right|-8=-5\quad :\quad x=-3\quad \mathrm{or}\quad \:x=3

Steps:

\left|x\right|-8=-5

\mathrm{Add\:}8\mathrm{\:to\:both\:sides}, \left|x\right|-8+8=-5+8

\mathrm{Simplify}, \left|x\right|=3

|f\left(x\right)|=a\quad \Rightarrow \:f\left(x\right)=-a\quad \mathrm{or}\quad \:f\left(x\right)=a, x=-3\quad \mathrm{or}\quad \:x=3

\mathrm{This\:Question\:Has\:2\:Answers}

\mathrm{The\:Correct\:Answer\:is\:x=-3\quad \mathrm{or}\quad \:x=3}

\mathrm{Hope\:This\:Helps!!!}

A circular field has a area of 14400 sq ft <br> What is the diameter of the field?
Bingel [31]

Answer:

240/sqrt(pi)

Step-by-step explanation:

We know that the area of a circle is $pi*r^2$, and we also know that the diameter of a circle is equal to $2r$.

Let's first make an equation for this problem.

pi*r^2=14400

Dividing both sides by pi, we get

r^2=14400/pi

Now, taking the square root of both sides gives us

r=120/sqrt(pi)

We are trying to find the diameter, which is twice the size of the radius.

Thus, we multiply the equation by two.

2r=240/sqrt(pi)
