Answer: D
Step-by-step explanation: ?
X^2-12x-9=0
Add 9 to both sides
x^2-12x=9
Add (b/2)^2 to both sides
x^2-12x+36=45
Factor
(x-6)^2=45
So C is the answer
Answer:
47 degrees
Step-by-step explanation:
Quadrilaterals add up to 360
The two dashes and the dashes imply that angle V and angle X are congruent.
128 + 138 = 266
360 - 266 = 94
94 / 2 = 47
Number of raptors in 2015: 234
% success: between 35% and 40%
Formula
% =: [number of success rescues / number of total rescues] * 100 =>
number of success rescues = % * number of total rescuess / 100
Number of success rescues:
a) 35 * 234 / 100 = 0.35 * 234 = 81.9
b) 40 * 234 / 100 = 0.40 * 234 = 93.6
Then, the number of raptor rescues that were succesfull was about 82 to 94.
