Hello Guest,
This question has been answered by Melody in the link below (It looks like a great and detailed explanation):

If you have any more question please let me know.
11* 10 is the smallest multiple of 11 that is greater than 100
and 11*9 is greatest multiple of 11 less than 100
110-99= 11
Expanding this would give us
\(729x^6+1458ax^5+1215a^2x^4+540a^3x^3+135a^4x^2+18a^5x+a^6\)
We know that the \(x^4\) is \(59535\)
So, \(1215a^2 = 59535\)
Giving us \(a^2=49 \)
\( a=\sqrt{49},\:a=-\sqrt{49}\)
\(a=7,\:a=-7\)

Yep it was an error on my side
Thanks for catching it guys!!!!

Who is right?
Hello, I agree
Here is the graph for proof:

a - 2b
(4 - 2i + 7)+2(3+2i-5i)
17-8i
They are all the same because they all use a similar method:
It is the quickest way to solve it!!!
I hope you have a great day!
Just look at the question above and my work.
Look closely, Im sure you will understand.
If you have any questions let me know
SOHCAHTOA for reference
Tan(theta) = 3/4
opposite/adjacent = 3/4
That means the opposite side is 3 and the adjacent side is 4
Using the Pythagorean Theorem
c = sqrt(3^2 + 4^2)
c = 5
cosine(theta): adjacent/hypotenuse
cosine(theta): 4/5
