Is you add all the ones you get 9 and if the mean is 10 sum of numbers/number of numbers so N has to be 91 because 91+9=100 100/10(number of numbers)=10
Answer:
You must add 9/4 in order to make this a perfect square.
Step-by-step explanation:
To make any binomial into a perfect square trinomial, you have to take the middle term (-3), cut it in half (-3/2) and then square it (9/4). This will give you the constant to make a perfect square trinomial every time.

Since 2 and 3 are multiples of 6, we know that the next time Tree C flowers both Tree A and B will too.
Answer:
first stage=420km
second stage=360Km
Step-by-step explanation:
Hi!
To solve the problem follow the steps below
1. We will call X to the first stage and Y to the second stage.
2. Raise the equations taking into account the following
the sum of both stages is 780km
X+Y=780km
the first stage has 60km more than the second
Y+60=X
X-Y=60
3. Add the equations found above
X + Y =780
X - Y =60
------------------------
2X=840
Solving for X=840/2=420Km
use one of the equations obtained in step 2, to get the value of Y
Y+60=X
X-60=Y
420-60=Y
Y=360km
