The correct answer is 6 - sqrt(6)
We know this because when we solve with the quadratic equation, the numbers come out with a constant plus and minus the discriminant under a square root symbol. You can see that below in the quadratic equation.
So seeing that one answer is 6 + sqrt(6), we can assume 6 is the discriminat and 6 is the constant. Thus giving us the new answer as well.
Answer:
2n + 2
Step-by-step explanation:
To get the answer you must do distributive. This means you have to multiply 2 and N and 2 and 1. Next, after you multiply these answers you put them together with whatever operation sign is there. In this case, the operation sign here is an addition. Therefore the answer would be 2n + 2.
Answer:
Step-by-step explanation:
Susan works faster
if you solve 8 problems in 20 minutes, that is faster than 1 problem per minute because even once you do 5 problems you are at 25 minutes and that is longer than the 20 minutes
V= visits
16v= 336
You would multiply 16 by v to find the money earned by the visits.
Divide 16 into both sides.
336/16= 21
v= 21
The gardener made 21 visits.
I hope this helps!
