Answer: 14

Step-by-step explanation:

We arrange the number as -3, 1, 7, 8, 18, 19, 42, the old median is 8.

But the median has change to 11 when the number is add, which means that the number is between 7 and 18.

(8 + x)/2 = 11 Where x is the new number

8 + x = 22

x = 14

The perimeter of a shape is the sum of its side lengths

The expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

<h3>How to determine the perimeter of the shape</h3>

The side length of the frame is given as l

So, the perimeter of the frame is

: $P = 4l$

When 2 inches are added to each length, the perimeter of the frame becomes

$P =4(l + 2)$

Expand

$P =4l + 8$

Hence, the expressions for the perimeter of the frame are 4(l + 2) and 4l + 8
