Answer:
n+7
Step-by-step explanation:
Sum means add, so it's just n added to 7:
n+7 :)

Answer:
B. {16, 19, 20}
Step-by-step explanation:
The <em>triangle inequality</em> requires for any sides a, b, c you must have ...
a + b > c
b + c > a
c + a > b
The net result of those requirements are ...
- the sum of the two shortest sides must be greater than the longest side
- the length of the third side lies between the difference and sum of the other two sides
__
If we look at the offered side length choices, we see ...
A: 8+11 = 19 . . . not > 19; not a triangle
B: 16+19 = 35 > 20; could be a triangle
C: 3+4 = 7 . . . not > 8; not a triangle
D: 5+5 = 10 . . . not > 11; not a triangle
The side lengths {16, 19, 20} could represent the sides of a triangle.

<em>Additional comment</em>
The version of triangle inequality shown above ensures that a triangle will have non-zero area.
The alternative version of the triangle inequality uses ≥ instead of >. Triangles where a+b=c will look like a line segment--they will have zero area. Many authors disallow this case. (If it were allowed, then {8, 11, 19} would also be a "triangle.")
Answer:
f(6) = 10, f(10) = 30, f(20) = 80
Step-by-step explanation:
Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.
Let
x--------> <span>the unknown scale size
we know that
N 1---------> 2.618
N 2---------> x
N 3---------> 1
N 4---------> 0.618
to obtain the size N 4 ----> multiply the size N 3 by 0.618
so
to obtain </span> the size N 2 ----> multiply the size N 1 by 0.618
size N 2=2.618*0.618------> 1.6179
x=1.618
the answer is
the unknown scale size is 1.618
