Answer:

x = 28

Step-by-step explanation:

Here's my work,

1/4x + 17 = x -4

So what to do first, we add 4 on both sides like so...

1/4x + 17 = x -4

<u>       +4         +4</u>

1/4x + 21 = x

Now to simplify, and isolate the variable.

1/4x + 21 = x

<u>-1/4x         -1/4x</u>

21 = .75x

Here we can finally divide. 21/.75 is 28 and .75x/.75 is x that means we are left with,

28 = x

If you need me to go over it again let me know! Hope this helps and have a great day!

AREA ADDITION AND SUBTRACTION ASSISTANCE?
Tom [10]

The shaded area is a segment. The area of a segment is

A_{segment}=A_{sector}-A_{triangle}.

You know radius that is the side of isosceles triangle and measure of angle between two equal triangle sides, then

A_{triangle} =\dfrac{1}{2} a\cdot a \sin \alpha=\dfrac{1}{2} 18.6\cdot 18.6 \cdot  \sin 123^{\circ}=172.98\cdot  \sin 123^{\circ}=145.07 sq. m..

The area of sector is A_{sector}=\dfrac{r^2\cdot \alpha}{2}= \dfrac{(18.6)^2\cdot 0.68\pi}{2}=117.63\pi=369.53 sq. m..

Then A_{segment}=369.53-145.07=224.46 sq. m.

Answer: A_{segment}=224.46 sq. m.
