Answer:
84
Step-by-step explanation:
6 times 7 is 42
42 times 2 is 84
7/50 = 0.14 therefore In order to write it as a fraction out of 100 you move 2 decimal to the right.
Therefore, the answer for the first box is 14/100
The last box obviously being 0.14
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Answer:
Step-by-step explanation:
x²- y² = (x+y) (x-y)
x² + xy = x(x+y)
x² + 2xy + y² = (x+y) (x+y)
