Answer:
4n^2-20n+25
Step-by-step explanation:
(-2n+5)^2
=4n^2-20n+25
Point-slope form is y - y1 = m(x - x1). If you apply that point and the slope to the formula (hence the name point-slope), you'd get y - 10 = -5(x + 8).
Hope this helps! :)
REVISE: I accidently put y instead of x in the -5(x + 8) part. It's fixed now.

Answer:
866.64
Step-by-step explanation:
40/2 = 20
A = πr²
3.14*20² = 1256
52/2 = 26
3.14*26² = 2122.64
2122.64 - 1256 = 866.64
(13 + 47) (21 + 79) =
60 + 100 =
160
