<h2>Answer:</h2>

x = {3,4,7,12}

n = {12,7,4,3}

(upside down)

<h2>Step-by-step explanation:</h2>

N = {1,2,3,4,5....}

\:

<h3>if n = 1</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(1) + 6}{1 - 2}}

\sf{x = \frac{2 + 6}{-1}}

\sf{x = \frac{8}{-1}}

\sf{x = - 8}

  • x not N

\:

<h3>if n = 2</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(2) +6}{2-2}}

\sf{x = \frac{4 + 6}{2 - 2}}

\sf{x = \frac{8}{0}}

\sf{x = \infty }

  • x not N

\:

<h3>if n = 3</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(3) +6}{3-2}}

\sf{x = \frac{6 + 6}{1}}

\sf{x = \frac{12}{1}}

\sf{x = 12}

  • x is N

\:

<h3>if n = 4</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(4) +6}{4-2}}

\sf{x = \frac{8 + 6}{2}}

\sf{x = \frac{14}{2}}

\sf{x = 7}

  • x is N

\:

<h3>if n = 5</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(5) +6}{5-2}}

\sf{x = \frac{10 + 6}{3}}

\sf{x = \frac{16}{3}}

  • x not N

\:

<h3>if n = 6</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(6) +6}{6-2}}

\sf{x = \frac{12 + 6}{4}}

\sf{x = \frac{18}{4}}

  • x not N

\:

<h3>if n = 7</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(7) +6}{7-2}}

\sf{x = \frac{14 + 6}{5}}

\sf{x = \frac{20}{5}}

\sf{x = 4}

  • x is N

\:

<h3>if n = 12</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(12) +6}{12-2}}

\sf{x = \frac{24 + 6}{10}}

\sf{x = \frac{30}{10}}

\sf{x = 3}

  • x is N

\:

<h3>conclusion</h3>
  • I found the pattern of numbers that the value of n is 3, 4, 7,12
  • For x, I found the pattern of numbers that the value of x is 12, 7, 4,3

I’ll give you brainliest for the first person with an answer
raketka [301]

Answer:

1296mm^2

Step-by-step explanation:

Surface Area of the Rectangular Prism to the left on top of the box:

Area of square = lw, 9mm * 9mm = 81mm, then multiply by 2 because 2 of the squares are a part of the surface, giving <u>162mm^2</u>

Area of a rectangle =lw, 9mm * 9mm = 81mm, then multiply by 2 again, because 2 rectangles are a part of the surface, giving <u>162mm^2</u>

So, the total surface area of the rectangular prism to the left on top, is 324mm^2

Surface Area of the Triangular Prism:

Area of a triangle: 1/2bh, and our base length would be 12, because we have to subtract 9 from 21 since the base length of the triangle isn't stated. Anyways, A = 1/2bh, so A = 1/2(12)(9) = 54mm^2, but multiply by two, so we get <u>108mm^2</u>.

Area of the rectangle: lw, so 15mm * 9mm = <u>135mm^2</u>

So, the total surface area of the triangular prism is 243mm^2

Surface Area of the Rectangular Prism at the bottom:

Area of the long rectangles in front = lw, 21mm * 9mm = 189mm^2, multiply by 2, <u>378mm^2</u>

Area of the rectangles to the side = lw, 9mm * 9mm = 81mm^2, multiply by 2, <u>162mm^2 </u>

Area of the rectangle at the very bottom = lw, 21mm * 9mm = <u>189mm^2</u>

So, the total surface area of the rectangular prism at the bottom is 729mm^2

Add all the total surface areas of each shape to get the total surface area of the figure:

324mm^2 + 243mm^2 + 729mm^2 = 1296mm^2

The surface area of the figure above is 1296mm^2
