For every
, we have

So, negletting the first term, each term of the sum is greater than 1, which implies

Which means that the series diverges.

Here we go ~

[ add 2 on both sides ]

[ form identity : a² + b² + 2ab ]

[ a² + b² + 2ab = (a + b)² ]



so, the value of required expression is 6
[usually positive value is considered, but if asked the value can be either positive or negative]
Answer:
The last one.
Step-by-step explanation:
The 1/2 slope has to be positive because the graph goes upward from the left to the right. If you plug in (3, -2), a possible point on the line, you get that 1=1, which is seemingly true.
Answer: -11
Step-by-step explanation:
2(-3) - 5(1) = -11
Find the median of this data
21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40
Now the median should be 50 so take 50 - 40 = 10
The missing number from the data is 10
