Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:

Introducing the proportionality constant, we can write:

Using the first set of given values of x and y, we get:

This means, the relation between y and x is:

We have to find y if x = 20. Using this value in above equation, we get:

Thus y would be 25 if x is 20.

Answer:
2x + 6
Step-by-step explanation:
The area of a square is the square of the side length:
A = s²
We know that the area of the square is 4x² + 24x + 36.
4 is 2², and 36 is 6². 24 is double 2 times 6.
Therefore, this is a perfect square trinomial:
A = 4x² + 24x + 36
A = (2x + 6)²
Therefore:
s = 2x + 6
You didn't put any options but any ratio that 4.2:1 doesn't go into is not equivalent.
Hope this helps :)
