Is there a value of n for which there could be a triangle with sides of length n, 2n, and 3n? explain

None

Step-by-step explanation:

There is no value for N if you try 30 it will go like this

2(30) = 60 + n = 90

3(30) = 90

your first two side have to be greater than your third

2(12) = 24 + n = 36

3(12) = 36

2(145) = 290 + n = 435

3(145) = 1305

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
