Answer:

n equals -1

Step-by-step explanation:

You basically distribute, or multiply -6 and 4 and get -24 and -6 times -3 to get a positive because a neg times a negative is a positive. Then you combine like terms and simplify. Hope this helps you!

Answer:N=-1

Step-by-step explanation: Distributive property first.

(-6 times 4n) (-6 times -3)

39-3n=-24n+18

Add 3n to -3n and -24n. (Doing this will cancel out -3n.

39=-21n+18

Then subtract 18 from 18 and 39.

21=-21n

Divide -21n and 21 by -21 to isolate the variable and cancel out the coefficient.

N=-1

The correct option is: Option (B) \sum_{i=1}^{7} (5i-2)

Explanation:

First thing is that the difference between each number in the series with the next number is 5. It means it must be the multiple of 5. There are two options that contain multiples of 5: Option B and Option D. Now in the option D, the upper limit is 6. If we put 6 in the expression: 5(6)-2, the last term would be 28. However in the series given in the question, the last term is 33. Hence 5(7) - 2 = 35 - 2 = 33 which is Option B.

When i=1: 5(1)-2 = 3
When i=2: 5(2)-2 = 8
When i=3: 5(3)-2 = 13
.
.
When i=7: 5(7)-2 = 35-2 = 33
Hence the correct option is (B).
