A triangle has 3 side, this makes no sense. Explain please.
Answer:
B
Step-by-step explanation:
3% = 3/100
So we can eliminate the first answer.
The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.
As a result, we eliminate the third answer and remain with one reasonable answer
Step-by-step explanation:
3(x+3)=12
3x+9=12
3x=12-9
3x=3
x=1
