Answer:
200. 200 200 200 200 200 is the answer
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
9n - 2 - 6n - 3
(9n + -6n) + (-2+-3)
=3n -5
