Answer:
The answer is : 70288.46
Step-by-step explanation:
Your father earned $34,000 per year in 1984.
The CPI in 2014 is 215 and the CPI in 1984 is 104.
The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.
The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)
= 70288.46
P(7,6), Q(1,6), R(4,2)
We have PQ parallel to the x axis. We'll call that the base,
b = 7 - 1 = 6
The altitude is then the y difference h = 6 - 2 = 4
The area is 
Answer: 12 square units
In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:
(7,6), (1,6), (4,2)
(1,6), (4,2), (7,6)
The area is then half the absolute value of the sum of the cross products:

Your answer can only be simplified to
256x^10 - 384^8 - 448^6
A) x=4
B) x= -3
C) x= -1/6
D) x=24
