Answer:

Step-by-step explanation:
The given system of linear equations is:

We have to solve the equations for the values of
.
Let us use elimination method in which we eliminate one of the variables from the two variables.
For this, let us multiply the first equation by
and second equation by 
Now, the equations become:

Now, let us add (1) and (2):

Using the equation:

Putting value of
:

So, the answer to the system of linear equations is:

Answer:
<h2>Yes they are congruent by SSS criterion </h2>
Step-by-step explanation:
AC=DC. (Given in figure)
AB=BD. (Given in figure
BC=BC. (Common)
that means triangle BAC is congruent to triangle BDC by SSS criterion.
I believe the answer would be (1) because they are not directly related
That will be the second one, square root of 34
