Determine whether the three lengths can form a triangle.

5, 15, 10

some one said that this makes a straight line

No.

Step-by-step explanation:

Given side lengths . We can only form a triangle if two sides added up are larger than the third side.

So all three must be true:

We can see that if:

We have:

Since one of the equations is false, we cannot form a triangle.

Option A is correct.

Step-by-step explanation:

Stocks are higher risk than most other securities in a mutual fund, but when averaged with the risk of the other securities, mutual fund risk is not as high as stock risk. Stocks are riskier as, in a very short period of time, the stock price could double or could collapse. This is not the case with mutual fund because it owns hundreds of stocks.
