Hi!

The correct answer is A.

The mirror is 4 feet wide.

The wall is 20 feet wide.

The distance x on each side of the mirror: x + x

4 feet wide + x + x = 20 feet wide

The mirror 4 feet wide + the distance x on each side of the mirror = the wall is 20 feet wide

in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope: ​
user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒  \frac{y2-y1}{x2-x1}

<u>Let's set the variables</u>:

   (x1, y1) --> (-9, 2)

   (x2, y2) --> (9, 2)

<u>Now let's plug them in:</u>

  Slope = \frac{2-2}{9--9} =\frac{0}{18} =0

<u>Thus the slope of the line is 0.</u>

Hope that helps!

To find the superficial area of a prism you have to do base perimeter * height

So find the perimeter of the right triangle: 9+8+5 = 22 yd

Then find the superficial area 22*12 = 264 yd^2
