With #90 plz i need to figure it out

14.4 inches to the nearest tenth.

Step-by-step explanation:

The square has area x^2 where x is the length of each side so:

x^2 = 13

x = √13.

The perimeter is the distance all around the square and this is  4x so we have the answer 4 *√13

14.422 inches.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
