None of the statements are true,
Proof:
Solve for x over the real numbers:
2 x^2 + 12 x = 32
Subtract 32 from both sides:
2 x^2 + 12 x - 32 = 0
2 x^2 + 12 x - 32 = 2 (x^2 + 6 x - 16):
2 (x^2 + 6 x - 16) = 0
Divide both sides by 2:
x^2 + 6 x - 16 = 0
x = (-6 ± sqrt(6^2 - 4 (-16)))/2 = (-6 ± sqrt(36 + 64))/2 = (-6 ± sqrt(100))/2:
x = (-6 + sqrt(100))/2 or x = (-6 - sqrt(100))/2
sqrt(100) = sqrt(4×25) = sqrt(2^2×5^2) = 2×5 = 10:
x = (-6 + 10)/2 or x = (-6 - 10)/2
(-6 + 10)/2 = 4/2 = 2:
x = 2 or x = (-6 - 10)/2
(-6 - 10)/2 = -16/2 = -8:
Answer: x = 2 or x = -8
I believe that is C. Statistical question.
I know it’s not B because that has nothing so do with the question so you’re good there. While A could be a potential answer, it says a question that can be answered by collecting data, whereas the mean would actually be that data and not the question that can be answered so C would be the only choice left.
Answer:
Basically what you want to do is get x by itself by adding -14 to the other side
Then you get 3x = 60
Next you divide 60 by 3 and get 20
<h2>X = 20</h2>
Answer:
0
Step-by-step explanation:
Imagine that you have zero cookies and you split them evenly among zero friends. How many cookies does each person get? See? It doesn't make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.
We know that
in the triangle ABC
∡A+∡B+∡C=180°
∡C=180-(50+100)-------> ∡C=30°
triangle ABC and triangle XYZ are similar
so
∡X=∡A
∡Y=∡B
∡Z=∡C
hence
∡Z=30°
the answer is∡Z=30°
