Answer:
Step-by-step explanation:
(x+5)² = 36
x+ 5 = ±√36 = ±6
x = -5 ±6 = 1, -11
By the binomial theorem,

where

Then the coefficients of the
terms in the expansion are, in order from
to
,





Basically, solve for n, then find aanother tha is solve for m
8n=-3m+1
divide both sides by 8
n=-3/8m+1/8
and find m
8n=-3m+1
minus 1 both sides
8n-1=-3m
divide both sides by -3
-8/3n+1/3=m
m=-8/3n+1/3
Answer:
C.
Step-by-step explanation:
Since the radius of the circle is 12 units, we can calculate the circumference.
2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.
The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.



1 * x = 4 * 4 * pi
x = 16pi
So, your answer is C.
Hope this helps!
