Ответ:
La respuesta es tres mi amigo.
Step-by-step explanation:
El numero es 3 Porque
3 × 3 = 9
9 × 2 = 18
18 - 18 = 0
aquí hay otro método
Formando una ecuación: 18 - 2x ² = 0
donde: 18 = 2x²
entonces: 9 = x²
respuesta: 3 = x
Ответ:
Yes, 4 is the constant of proportionality
Step-by-step explanation:
The constant of proportionality here is the value you multiply x by to get y. if you divide 12/3, 24/6, 36/9, 60/15, the answer to all of those is 4. Because the multiplier is the same for each one they are all proportional.
