To tell whether the <span>the sequence is arithmetic, we try to see if there is a common difference between the terms in the sequence. We do as follows:
1 1/2 - 1 1/3 = 1/6
1 1/3 - 1 1/6 = 1/6
Therefore, the sequence is arithmetic and the common difference is 1/6. Hope this answers the questions. Have a nice day.</span>
Convert the percent into a decimal by moving the percent sign by two places to do left. 80% => 0.80.
Then multiply: 90 * 0.80 = 72
D. Have the same number of valence electrons
The answer would be 56n^2 + 19n - 15
Multiply 8n with 7n to get 56n^2, then multiple 8n with 5 and you get 40n, then multiple -3 with 7n to get -21n, then -3 times 5 which gives you -15. Simplify and that is the answer you would get.
Answer:
The correct answer for that is (98)
