Step-by-step explanation:
D. people do not have to have a good or service that another person wants
Reason: Money gives people a universal unit of value. For example, If I needed a toothbrush and I have a pair of scissors, In order for me to get a tooth brush is to trade my scissors with someone else who has a tooth brush and wants scissors. As you can see, this isn't practical. If I had money, I will only need to find someone who has a tooth brush.
Answer:
-22
Step-by-step explanation:
First do r(3) by replacing x with 3 in r:
2*3^2 + 2 = 2*9 + 2 = 18 + 2 = 20
Then replace r(3) with 20 to do q(20):
-20-2 = -22
8 x 1 = 8
8 x 1/2 = 4
8+4 =12
therefore, 8 x 1 1/2 = 12
