Answer:
x = 30
Step-by-step explanation:
First you would add the like terms, which are 2x and 4x, which gives you 6x. Now the equation would read 6x + 6 = 180
You need to get rid of the six, and since what you do to one side of the equation must be done to the other, you need to subtract 6 from both sides to cancel out the 6 on the left side of the equation. The equation is now 6x = 180. Now you need to divide both sides by 6, which gives you x = 30.
Answer: Martha holding on to stocks that have poor market performance for three years is clearly an investing mistake.
Sanjay, Silvia and Sabrina seem to be making good investment decisions.
Ricardo is probably making a good decision too.
Step-by-step explanation:
I'm not sure that I can be of great help, because I have not read the Tutorial for this unit.
For me it is hard to tell about Ryan. I wonder what the Tutorial says. The fact that he has complete faith in a company may mean he has done a lot of research and understands the potential for the company to be profitable. But his faith in the company may be based on advertising or familiarity with a product. There may be other opportunities to invest in lesser known companies-- taking a risk may lead to opportunity. Maybe he should consult his stock broker or financial adviser.

Answer:
V =192 pi or approximately 602.88 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
We need to determine the radius
r = d/2 = 8/2 =4
V = pi (4)^2 *12
V = pi *16*12
V =192 pi
We can approximate pi by 3.14
V = 192* 3.14
V =602.88 cm^3
Answer:
B; because it has two points where x is once 2 and once -4
