What is the series you are referring too?

The answer is 54x so yeah
Answer:
67
Step-by-step explanation: Given the quadratic equation $z^2 + bz + c = 0$, Vieta's formulas tell us the sum of the roots is $-b$, and the product of the roots is $c$. Thus,
\[-b = (-7 + 2i) + (-7 - 2i) = -14,\]so $b = 14.$
Also,
\[c = (-7 + 2i)(-7 - 2i) = (-7)^2 - (2i)^2 = 49 + 4 = 53.\]Therefore, we have $b+c = \boxed{67}$.
There are many other solutions to this problem. You might have started with the factored form $(z - (-7 + 2i))(z - (-7 - 2i)),$ or even thought about the quadratic formula.
This is the aops answer :)
187 cm squared.
Based on rectangle:
2L + 2W = 56
Draw the square and name your sides the following:
(W+4) , (L-2), (W+4), (L-2)
Because it’s a square, all sides are equal and we can remove and solve for one of the variables but keep in mind the parameter changed..
The new parameter is 56 minus 4cm + 8cm...keep in mind I used 4cm and 8cm because we have a 2 Lengths and 2 Widths.
Solving 60= 4 (w+4)
W= 11
So the side of our square is 11+4=15
L-2 = 15
L=17
So the area of the Rectangle is 11*17=187 cm squared.
Please let me know if it’s correct !
