Here’s the answer and each step I took to solve it. With the example I made on the side just continue to repeat that for each one to get the answers. You just replace that one number for the X to take the place for the next X value as you go down the table solving them.
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
<h3>What is the surface area of a truncated prism?</h3>
The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:
A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)
A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²
A = 276 cm²
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.

Step-by-step explanation:
Answer :
1
Step-by-step-explanation :
![{x}^{2} + 4x + 5 - {(x + 2)}^{2} \\ {x}^{2} + 4x + 5 - ( {x}^{2} + 4x + 4) \\](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%205%20-%20%20%7B%28x%20%2B%202%29%7D%5E%7B2%7D%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%205%20-%20%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%204%29%20%20%20%5C%5C%20)
![{x}^{2} + 4x + 5 - {x}^{2} - 4x - 4 = {x}^{2} - {x}^{2} + 4x - 4x + 5 - 4 = 5 - 4 = 1](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%205%20-%20%20%7Bx%7D%5E%7B2%7D%20%20-%204x%20-%204%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20-%204x%20%2B%205%20-%204%20%3D%205%20-%204%20%3D%201)
I have absolutely no idea goodluck with that
Now the reasoning of me not knowing is because my brain capacity is very low im just tryna get points I hope you find out the answer to that question good day sir
