Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4. 
Plug it in to check. 
(4)^2+4=20
16+4=20
20=20

Ultimately your final answer is X=4

Bezzdna [24]

Answer:


Step-by-step explanation:

The answer is c.


Proportional means a relationship of y = a constant multiplied by x


In this case, the constant is 7.


i.e. y = 7x


So if


x is 3, y is 21


x is 5, y is 35


x is 7, y is 49


and so on...


And there you have it.
