The formula for the distance between two points is

Note that, if two points have one coordinate in common, this formula simplifies to

(the first if they share the y coordinate, the second if they share the x coordinate).
So, these are the lengths of the sides:

(because they share the y coordinate)

(standard formula)

(because they share the y coordinate)

13: is b because 200/10 is 10
14: 74 x 6 = 444 so the answer is C
15: 18 x 6 = 108 so D
16: 17 x 6 = 102 apartments
Answer: Hence, Option 'A' is correct.
Step-by-step explanation:
since we have given that
Cost of per cans = $0.90
Let number of cans of Tuna be n
so, Total cost of n cans be

Amount of coupon Tuna get off on total purchase = $0.40
So, According to question,

Hence, Option 'A' is correct.
Answer:
No because they have different slopes
Step-by-step explanation:
(1 , 2) and (2, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-2)/(2-1)
m = 2
Answer: Both 4 barrels and 7 barrels of beer per crates of olives will allow both Germany and Portugal to gain from trade.
Step-by-step explanation: For every 1 crate of olives produced by Portugal, they will not be able to produce 3 barrels of beer in return. Therefore, for portugal to trade a crate of olives for barrels of beer more than 3 means they are gaining on the trade, in this case, they gain 1 (option A) and 4(option B) extra barrels of beer for every crate of olive traded with Germany. Likewise Germany gains in both cases because any exchange of barrels of beer that is less than 11 barrels of beer to a crate of olives is a gain for Germany. Therefore both 4 barrels and 7 barrels for a crate of olives will lead to both countries gaining.
