Answer:
x^2 = 121
x = 11 Im wanting brainliest
Step-by-step explanation:
Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm
6[13-2(4+1)]
Solve what is in the bracket first.
Parenthesis first.
6[13-8-2]
6(3)
18
Answer:
Mean = 50
Step-by-step explanation:
<em>Step 1: Write the mean formula</em>
Mean = sum of data/ total number of data
<em>Step 2: Calculate the sum of data</em>
35 + 40 + 45 +50 + 55 + 60 + 65 = 350
<em>Step 3: Find the total number of data</em>
Total number of data = 7
<em>Step 4: Calculate the mean</em>
Mean = sum of data/ total number of data
Mean = 350/7
Mean = 50
Therefore, the mean of this data is 50.

EXPLANATION
The nth term of the sequence is given by

Where
is the first term and
is the constant difference.
We were given that,
S we just need the common difference to write the nth term.
We can get that from another information given to us.
We were also given that the 4th term is 6. This gives the equation.
We substitute
to obtain
Or
This implies,

We substitute these values into the general formula to obtain,

This gives us,


Hence the nth term of the sequence is,
