Which ever expression is 3x + 21 + 10 ..... 21 + 10 = 31 .... So it'll be 3x + 31 .
The answer is b. Let me know if you need an explanation
Answer:The amplitude:30
so a:-30
the period is:12
so b: pi/6
Step-by-step explanation:
The answer is probably 30 or 60
Answer:
1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.
