Step-by-step explanation:
3) because thhe solution should be equal to the values that x and y could take to make the equation true
Answer: c)
Step-by-step explanation:
This can be done through trial-and-error. Use the pythagoreas' theorem
and if the left side of the equation is equal to the right, that is the answer.
(Do take note that c is the longest side.)
a)
![0.07^{2} +2.4^{2} =5.7649](https://tex.z-dn.net/?f=0.07%5E%7B2%7D%20%2B2.4%5E%7B2%7D%20%3D5.7649)
![2.5^{2}=6.25](https://tex.z-dn.net/?f=2.5%5E%7B2%7D%3D6.25)
Since
, a) is wrong.
b)
![17^{2} +30^{2} =1189\\ 34^{2} =1156](https://tex.z-dn.net/?f=17%5E%7B2%7D%20%2B30%5E%7B2%7D%20%3D1189%5C%5C%0A34%5E%7B2%7D%20%3D1156)
Since
, b) is wrong.
c) (answer)
![5^{2} +12^{2} =169\\13^{2} =169](https://tex.z-dn.net/?f=5%5E%7B2%7D%20%2B12%5E%7B2%7D%20%3D169%5C%5C13%5E%7B2%7D%20%3D169)
Since
, c) is correct.
d)
![(7x)^{2} +(12x)^{2} =193x^{2}\\(13x)^{2} =169x^{2}](https://tex.z-dn.net/?f=%287x%29%5E%7B2%7D%20%2B%2812x%29%5E%7B2%7D%20%3D193x%5E%7B2%7D%5C%5C%2813x%29%5E%7B2%7D%20%3D169x%5E%7B2%7D)
Since
, d) is wrong.

Answer:
30 ≥
Step-by-step explanation:
6 ≥ 1/2x + 21
-6 -6
1/2x ≥ 15
15/1 x 2/1 = 30/1
answer: 30
you keep the sign the same because you only flip the sign if you multiply or divide by a negative number
