1)
for a valid triangle two sides added together have to always be larger than the third
(otherwise it turns into a line)
12, 18, 6 would not be a valid triangle, because 12+6<=18
but 12, 18, 14 would be valid, because
12+18>14
12+14>18
18+14>12
2)lets start with an obvious right triangle and have the axis along the y and x axis like
so decide some x like -4 and some y like -3 and keep all other coordinates at 0:
A=(-4,0) B=(0,-3) and C=(0,0)
make it a bit more complicated (less 0s) by some x and y translation like (-2,3)
just add that to every point's coordinates and you get
A=(-6,3), B=(-2,0), C=(-2,3)
Third option, counting from the top.
Remember that we say that a limit exists, like:

if and only if:

and

Where the above two limits say that when we approach zero from the negative side (the first one) and from the positive side (the second one), we must get the same value.
Also, remember that the limit is an approximation through near points
Then, regardless the fact that f(0) = -2, we can see that as x approaches 0 from both sides, the value of the function approaches 4.
Thus, we can conclude that the limit of f(x) when x tends to zero is equal to 4.
The correct option is the third one.

Answer:
<h2>MN = 9.1 cm</h2>
Step-by-step explanation:
If MN is tangent of a circle then the angle M is a right angle.
We have a dimeter of acircle d = 8 cm.
Therefore the radius CM = 8 cm : 2 = 4cm.
In a right triangle CMN use the Pythagorean theorem:

Substitute CM = 4cm and CN = 9.9 cm:

<em>subtract 16 from both sides</em>
