Answer: D.
This is tricky.
Think of the equation as an equation for a line
where in this case.
or
You can see the slope of the graph is 
which means that for an increase of 1 degree Fahrenheit, the increase is .
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 
Degrees Fahrenheit
Since 
Statement 2, is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
which is ≠ 1)
An increase of degree Fahrenheit leads to an increase of 
not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.

Answer:
4√2 + 2√10
Step-by-step explanation:
Finding the perimeter here involves finding three point-to-point distances and then adding them up.
From (2, 2) to (6, -2) we have a change in x of 4 and a change in y of -4. We use the Pythagorean Theorem to determine the distance, which is the hypotenuse of a right triangle:
√( [4]² + [-4]² ) = 4√2. This is the length of the side connecting (2, 2) and (6, -2).
From (6, -2) to (5, 1), the distance is √( [-1]² + 3² ), or √10.
From (5, 1) to (2, 2), the distance is √( [-3]² + 1² ), or √10.
The perimeter is the sum of these three distances and is:
4√2 + √10 + √10, or 4√2 + 2√10
Answer:
168
Step-by-step explanation:
2(a - 3) + 2(4a - 10) =
= 2a - 6 + 8a - 20 =
= 2a + 8a - 6 - 20 = <u>1</u><u>0</u><u>a</u><u> </u><u>-</u><u> </u><u>2</u><u>6</u> ← the end
