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.
The answer to the question is b
$9 each hour she works + 7.50 fee
$7.50+$9h= $34.50
Answer:
331
Step-by-step explanation:
Add 74 + 46 + 57 = 177
Add 9 + 36 = 45
Add 45 + 46 = 91
Answer:
D = 32
Step-by-step explanation:
A+ B + E = 180 since they form a triangle
14+ 45 + E = 180
E = 180 -14-45
E =121
E on either triangle is the same since they are vertical angles
C+D+E = 180 since they form a triangle
27+ D + 121 = 180
D = 180-121-27
D =32
Answer:
AGE=150
Step-by-step explanation:
FHD and GHC are supplementary, so:
180-30=150
CHG is corresponding to AGE, so AGE=150
