Answer:
EBCG
Step-by-step explanation:
1) 50 - 87 = 23
2) 12 - 24= 288
3) 38.25 + 11.75= 50
4) 7 divided by 168= 24
This question is far easier to understand if we draw it out. I've included an image attachment to help show the relationships of the measurements. As we can see from the image, their positioning helps form a triangle that we can use the Pythagorean Theorem to find the connection range.
The Theorem is

where a and b are the legs and c is the hypotenuse.





So the answer to the nearest meter is 55 meters.

3. We have to calculate the area of wood present in the frame whose dimensions are given with the question.
Requires area = {(x + 3) × 1} + [(4 - 1) × {(x + 3) - (x - 2)}] = x + 3 + 3 × 5 = x + 18. (Answer)
4. The sum of four consecutive odd numbers where 2n + 1 is the smallest odd number will be
= (2n + 1) + (2n + 3) + (2n + 5) + (2n + 7)
= 8n + 16 (Answer)
