Answer:
Step-by-step explanation:
Let's factor the numerator and denominator first.
x^2+5x-6 is a quadratic in the form of x^2+bx+c.
If you have a quadratic in the form of x^2+bx+c, all you have to do to factor is think of two numbers that multiply to be c and add to be b.
In this case multiplies to be -6 and adds to be 5.
Those numbers are 6 and -1 since -1(6)=-6 and -1+6=5.
So the factored form of x^2+5x-6 is (x-1)(x+6).
x^2+9x+18 is a quadratic in the form of x^2+bx+c as well.
So we need to find two numbers that multiply to be 18 and add to be 9.
These numbers are 6 and 3 since 6(3)=18 and 6+3=9.
So the factored form of x^2+9x+18 is (x+3)(x+6).
So we have that:
We can simplify this as long as x is not -6 as
I obtained the last line there by canceling out the common factor on top and bottom.

Money must serve as a medium of exchange, a storehouse of value and a unit of account
Answer: Option B, D, and E
<u>Step-by-step explanation:</u>
Money, the term coined in terms of the following three services.
- Medium of exchange played as important role to facilitate transactions. Think scenario like without money, then all operations would be exchanged as one product or service exchange for another (barter system).
- To be in above, money must retain its value over time i.e store of value. Failure to save money for some time and still remain valuable in return would not resolve the double overlap of desires and therefore would not be accepted as a medium of exchange.
- Money also acts as a units of account and is a regular measure of the cost of goods and service exchanged. Knowing the value of a good or the price in cash, both the supplier and buyer can decide how much to deliver and how much to buy.
