Answer:
f(x) = -x^2 - 6x - 10
Step-by-step explanation:
Please write the original equation as f(x) = -(x + 3)2 - 1, as "(x + 3)2 is meaningless. We want:
f(x) = -(x + 3)^2 - 1, where " ^ " denotes exponentiation.
Expanding this, we get:
f(x) = -(x^2 + 6x + 9) - 1, or
f(x) = -x^2 - 6x - 9 - 1, or:
f(x) = -x^2 - 6x - 10 This matches the first answer choice.

Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:
C)4
Step-by-step explanation:
If the number is divisible by 9 the sum of its digit must be divisible by 9.
52,34p
Solution:
5+2+3+4+p=14+p
If we add 14 to 4
14+4=18
p=4
