(x +6 ) ( x- 6)
Step-by-step explanation:
Answer:
$677.18
Step-by-step explanation:
Data provided in the question:
Bill’s nominal income in 1990 = $1,009 per month
CPI value in the year 1990 = 149
CPI value in the year 2017 = 192
Now,
The Consumer price index ( CPI ) is given as :
CPI =
thus,
for the given case of year 1990
149 =
or
Real income in 1990 =
or
Real income in 1990 = $677.18
Answer: x=12
First, you do 8 squared = 4(4+x)
Then, you distribute and becomes a two-step equation.
64=16+4x.
So x=12.

Answer:
Step-by-step explanation:
If arccos (√3 / 2) = β, then cos β = adjacent side / hypotenuse = √3 / 2. This tells us immediately that the adjacent side length is √3 and the hypotenuse is 2. Via the Pythagorean Theorem, we know that the third side is 1.
This information rules out the 1st and 3rd answer choices.
Because cos 30° = adj / hyp = √3 / 2, we can conclude that the correct answer is the 4th one: 30°, 60°, 90°
