Answer:
Pretty good, how are you?
Answer:
7a^6b
Step-by-step explanation:
Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b
Note that the power of b in the second term is b^1 which is the same as b
I believe the correct answer would be that it has one solution which is 5. Calculating x for the quadratic equation, you will only get one value so it should be one solution. Hope this answers the question. Have a nice day.
For this case what you should do is take 15% of 22.50 and add it to the original price. We have then:
((15) / (100)) * (22.50) = 3.375
Then, we add to the original price:
22.50 + 3.375 = 25.875
round to the nearest cent
25.88
answer
C.$25.88
