<em>The complete question:</em></h3>
<u><em> </em></u><u>Harold uses the binomial theorem to expand the binomial </u>
<u />
<u>(a) What is the sum in summation notation that he uses to express the expansion?
</u>
<u>(b) Write the simplified terms of the expansion.</u>
Answer:
(a). 
(b).
Step-by-step explanation:
(a).
The binomial theorem says

For our binomial this gives

(b).
We simplify the terms of the expansion and get:



Answer:
The answer is 212.
Step-by-step explanation:
If there are 3 vendors that donated popcorn, and there are 636 bags, and they all gave the <em>same</em> amount of bags, then you would get the total (636) and divide it by the amount of vendors (3) which would give you 212.
Answer:
B. 6π
Step-by-step explanation:
If you look at the help image I attached, what we are given is in RED and what we solve is in BLUE.
First, draw a diagonal in the square. Its length is the diameter, but we don't know the exact value. Since two right triangles have been created, we use Pythagorean Therom to solve for the hypotenuse/diameter:



If diameter =
, then radius is
or
Circumference = 2πr
2π (
)
6π
I hope this helps!
Answer:
The solution of a system of equations is the point(s) that lies on both lines. Therefore if the 2 lines cross over each other then there is exactly one solution. If they have no solution it means they are parallel since they don't share a single point and if they are overlapping lines then there is an infinite amount of solutions since they share the same points.
In this case it must have 1 solution.
To find which point is correct you should be able to plug in the same point for the x and y of the equations so that they are valid.
For example in the equation y=2x and y=-1/2x we need to find the point in which will work for both equations. In this case 0,0 is correct (0=0, 0=0)
So lets plug in the points and find the correct solution:
A. -1=-2+5
-1=-3 - this isn't true since -1 cant possibly equal -3. Therefore this point is incorrect.
B. 3=-2+5
3=3 - this is valid
______________
3=-2(-2)-1
3=4-1
3=3 - this is also valid
Therefore B is correct
(-2, 3)
