Answer:
The length of DF must be between 21 and 53.
Step-by-step explanation:
In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.
EF + DF > DE
16 + DF > 37
DF > 21
Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.
DE + EF > DF
37 + 16 > DF
53 > DF
With these two in mind, we know that DF must be between 21 and 53
Answer:

Step-by-step explanation:
Given
f(x) = 
To evaluate f(a + 2) substitute x = a + 2 into f(x), that is
f(a + 2) =
= 
Answer:
$73.5
Step-by-step explanation:
The answer is simple, since he gets 5% every year, and its only been 1 year, just find 5% of 70 and add it together.
We can find 5% of 70 by multiplying 70 by .05.
70*.05=3.5
70+3.5=73.5
He will have 73.5 dollars.

It would be 48 cause one side is 8 and another is 6 multiple and the answer is 48
