Answer:
- first side: 55 cm
- second side: 60 cm
- third side: 50 cm
Step-by-step explanation:
The problem statement gives all the side lengths in terms of that of the second side. Let s represent the length of the second side in cm. Then the length of the first side is (2s-65), and the length of the third side is (s-10). The perimeter is the sum of all the side lengths:
165 = (2s -65) +s +(s-10)
165 = 4s-75
240 = 4s
60 = s . . . . . . . . second side
2s-65 = 55 . . . . first side
s-10 = 50 . . . . . . third side
In order, the side lengths are 55 cm, 60 cm, 50 cm.

40+2 is a answer to your problem
The answer is 277. If you use PEMDAS you would multiply 9x27. Then 2x31. Then add them 243+62. Then subtract 28. Which gives you 277
the answer is 3 because if you line them up in number order you get
1 1 2 3 3 4 5 and the middle number is 3
