Answer:
y=x2−4x+7
or you can do it is way y=(x−2)2+3
Step-by-step explanation:
Answer: 80 (choice B)
=========================================================
Explanation:
This is an interesting venn diagram. Each region is either a circle or some kind of arrow shape. The numbers in the regions correspond to the qualities mentioned. For example, the "55" in the circle outside the other arrow regions tells the reader that there are 55 secretaries who are reliable but don't possess any other quality. As another example, the 35 is inside the circle and the left-pointing arrow to tell us that there are 35 people who are reliable and organized.
What we want to find are the values that are in 3 or more regions. There's only two cases when this happens: The 15 and the 65 as they are in the circle, the double arrow, and one of the single pointing arrows. So we have 15+65 = 80 candidates that possess 3 qualities. No person has all four qualities because there isn't a value that's in all four regions at the same time. Or you could note that the left and right pointing arrows do <u>not</u> overlap which is a big clue that there's no way someone could possess all four qualities at once. It might help to trace out the figures using different colors so you can pull apart the four figures.

Answer:
The shorter sides are 17 2/3 cm long
Step-by-step explanation:
Yes, you explained it right.
Let's remember that an hexagon has 6 sides, so the perimeter is the sum of the lengths of all the sides.
I assume there are 3 longer sides and 3 shorter sides. (it could be 4/2, but not 5/1 based on the use of plurals in the question).
If it was a regular hexagon the perimeter would be 6x a side length.
But it's not a regular one, however we know the link between the various lengths. So, let's input what we know, taking x as the length of a short side:
162 = 3x + 3 (2x + 1) = 3x + 6x + 3
159 = 9x
x = 17 6/9 so 17 2/3 cm
