Answer:
There are no extraneous solutions
Reasoning:
An extraneous solution is a solution that isn't valid, it might be imaginary like the square root of a negative number.
first we want to isolate z:
1+sqrt(z)=sqrt(z+5)
^2 all ^2 all
(1+sqrt(z))(1+sqrt(z))=z+5
expand
1+2sqrt(z)+z=z+5
-1 -z -z -1
2sqrt(z)=4
/2 /2
sqrt(z)=2
^2 all ^2 all
z=4
Since there is one solution and it is a real number, there are no extraneous solutions.
Answer:
41 minutes 40 seconds
Step-by-step explanation:
10km = 10000m
10000/4 = 2500 seconds
2500/60 = 41.6666...
Hence, 41 minutes 40 seconds.
Answer:
cant help you out, there are no options
It should be m < a + m < b + m < c = 180.....sum of angles of a triangle
The answer is C: 5/12
Tangent= opposite side/adjacent side
Opposite side of H=5
Adjacent side of H=12
Tangent of Angle H= 5/12
Hope this helped!
