You welcome :)
I'm assuming that you mean

because if you meant

then u would simplify and you couldn't make it the subject.
Under this assumption, we start with

We multiply both sides by 

We expand the left hand side:

We move all terms involving u to the left and all terms not involving u to the right:

We factor u on the left hand side:

We divide both sides by 

Answer:
A. 6
Step-by-step explanation:
Using the Pythagorean theorem which states that: <u>Hypotenus² = Opposite² + Adjacent²</u>
Where: hypotenus = 10, opposite = x, adjacent = 8
So:

Solving for x

Collect like terms to make x the subject of formula


square root both sides of the equation to find the value of x

Therefore: Option A is correct
Step-by-step explanation:
Tn=ar^(n-1)
r=-10/-5=2
a=-5
Tn=-5×(2)^(n-1)
Tn=-5•(2)^(n-1)
an=5•(2)^(n-1)
Answer:
2
Step-by-step explanation:
The outlier here is greatly above all of the others, the mean is the sum of all of the numbers/the amount of numbers. So, if we exclude the outlier, the sum of all of the numbers would decrease
