Let the length of the shortest side be x, then the length of the second side is x + 4 and the length of the third side is 2x - 4.
Then, x + x + 4 + 2x - 4 = 52
4x = 52
x = 52/4 = 13
Therefore, the lengths of the sides of the triangle are: x = 13, x + 4 = 13 + 4 = 17 and 2x - 4 = 2(13) - 4 = 26 - 4 = 22.
i.e. 13, 17, 22
Answer: 4
Step-by-step explanation:
We have
M(X) = (X + 5)/(X - 1)
N(X) = X - 3
So,
M(N(X)) = [(X - 3) + 5]/[(X - 3) - 1]
<h3>M(N(X)) = [X + 2]/[X - 4]</h3>
The M(N(X)) domain will be:
D = {X / X ≠ 4}
4 ∉ to the M(N(X)) domain, otherwise we would have a/0, which is not possible (a denominator with zero). An equivalent function would be
H(X) = 1/(X - 4)
Earthquakes with a magnitude of 3 are usually not felt or are only felt by a few people at rest (mostly on higher floors of buildings).
