Option (C.) is the right choice!
It's about constructing the perpendicular bisector..!!!

Answer:

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Step-by-step explanation:

We start with the equations:

and

Rearranging the second equation to make y the subject results in;

Substituting into the first equation gives us:

and

The solutions remain as (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Answer:

According to the map, the length of the canal is 16.4 centimeters.

Step-by-step explanation:

If the real length of Panama Canal = 20 kilometers

and the canal's length on the map = 4 centimeters

Then, the scale factor is

=

=

If the actual length of the Panama Canal = 82 kilometers

The length of the canal on the map = Actual length × Scale factor

=

= 16.4 centimeters

So, the canal's length on the map is 16.4 centimeters.
