Answer:
First side is 19, second side is 38 and third side, the longest is 43.
Step-by-step explanation:
Let's call the first side a.
The second side, being twice as long as the first, is 2a.
The third side is 2a+5.
The equation is:
a+2a+2a+5=100, since 1 metre is 100 centimetre.
5a+5=100
5a=95
a=19
First side is 19, second side is 38 and third side, the longest is 43.

Determine the reciprocal
If a number is x, the reciprocal is: 1/x
So, the reciprocal of
is:


So, we have:


Evaluate all exponents

Take inverse of 9/49

Hence, the reciprocal of
is 
C is (0,-5) and D is (1,0)
You must calculate h(24) first. h(x) = x^2 + 1, so h(24) = 577.
g(x) = 3x, so g(577) = 3(577) = 1731 (answer). We don't need f(x).
Huh? Can you put a picture?
