Length of side of new square is 17 inches

Step-by-step explanation:

  • Step 1: Let the length of the side of the old square be x. Then length of side of new square = x + 3 and Perimeter of new square = 40 + 2x

Perimeter of a square = 4 × side

⇒ 4(x + 3) = 40 + 2x

⇒ 4x + 12 = 40 + 2x

⇒ 2x = 28

⇒ x = 14 inches

  • Step 2: Find length of side of the new square

⇒ x + 3 = 17 inches

Which statement BEST describes why this set of ordered pairs is NOT a function?
UNO [17]

We have x = 4 repeating itself

If we graph the two points (4,1) and (4,20), then we see the relation fails the vertical line test.

The input x = 4 leads to more than one output y = 1 and y = 20 simultaneously.

This is why we don't have a function.
