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.
For company a ( $376 + $12 an hr) it would take 2 hours because 376+12= 388+12= 400 (376 + (12 x 2) )
for company b, ( $280 + $15 ) it would take 9 hours because 280 + 15 = 295 + 15 =
310 + 15 = 325 + 15 = 340 + 15 = 355 + 15 = 370 + 15 = 385 + 15 = 400 (280 + (15 x 8))
376 x (12 x 2)
376 x 24 = 400
280 x (15 x 8)
280 x 120 = 400
1) a = 2 hrs
b = 8 hrs
2) $400
Answer:
No im pretty sure its not a solution.
Step-by-step explanation:
See if “z” is 2 than the answer to the solution would be 20
I hope this helps.
When the circumference is divided by the diameter, the result can go beyond 100,000 decimal points, so to make calculations easier, pi is rounded to 3.14, or shown as the symbol π. Pi helps you calculate the area of the circle. ... Lenart says pi is useful in many fields that use math.
Answer:
Step-by-step explanation: 3+2=5 and 2+4=6 so 56 is your answer just like 32+24
