Answer:
x=20
The side lengths form a 345 triple
Step-by-step explanation:
345 triangles have 3, 4, and 5 as their lengths
If we divide all of them by 4 we get..
12/4=3 and 16/4=4 that means we are missing 5

Answer:
D
Step-by-step explanation:
The arcsine (
) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when

we have that

This gives us the domain
of the function 
The range of the function
is
so the range of the function
is the same (options A and C are false).
When x=-4,

So, option B is false and option D is true.
Ans: y = x + 4
