Nyatakan pernyataan berikut sama ada benar atau palsu.Jika x=2, maka x+14=15
- A.
Benar
- B.
Palsu
Correct Answer
B. PalsuExplanation
The statement "Jika x=2, maka x+14=15" translates to "If x=2, then x+14=15" in English. However, when we substitute x=2 into the equation, we get 2+14=16, which is not equal to 15. Therefore, the statement is false.Rate this question:

Nyatakan pernyataan berikut sama ada benar atau palsu.20 ialah faktor bagi 2 dan 6+12=20
- A.
Benar
- B.
Palsu
Correct Answer
A. BenarExplanation
The statement is true because 20 is indeed a factor of 2 and 6+12 does equal 20. A factor of a number is a whole number that divides evenly into that number without leaving a remainder. In this case, 20 can be divided by 2 without leaving a remainder, making it a factor of 2. Additionally, 6+12 does equal 18, which is not equal to 20. Therefore, the statement is true.Rate this question:

Nyatakan pernyataan dan akas berikut sama ada benar atau palsu.Pernyataan: Jika x=2, maka x-1=1Akas: Jika x-1=1, maka x=2
- A.
Benar
- B.
Palsu
Correct Answer
A. BenarExplanation
The given statement and its converse are both true. This can be proven by substituting x=2 into the original equation x-1=1, which gives us 2-1=1, and therefore x=2. Thus, the original statement is true. Additionally, if we assume x-1=1, then by adding 1 to both sides of the equation, we get x=2. Hence, the converse statement is also true.Rate this question:
