156. you basically just need to multiply 78 by 2
The ratio is 4:5 girls to boys
a_{10} = \frac{177147}{65536} is solution of arithmetic progression (AP).
What is arithmetic progression (AP) in math?
- The difference between any two consecutive numbers in an arithmetic progression (AP) is always a fixed amount.
- The AP cost per invoice is calculated by dividing the total number of invoices paid over a certain time period by all the expenditures incurred to pay those invoices over that same time period.
- An accurate assessment of a company's AP efficiency can be made using this metric in conjunction with other accounts payable measures.

If you think about this equation as a line, then in order to have an infinite number of solutions is to have another equation that describes the same line.
So, for example 3y=2x-15 would be one of those.
Answer:
(D) -k2 + k - 13
Step-by-step explanation:
Pulling out like terms :
2.1 Pull out like factors :
-k2 + k - 13 = -1 • (k2 - k + 13)
Trying to factor by splitting the middle term
2.2 Factoring k2 - k + 13
The first term is, k2 its coefficient is 1 .
The middle term is, -k its coefficient is -1 .
The last term, "the constant", is +13
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is -1 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14
13 + 1 = 14
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-k2 + k - 13
