a square has a side length of (5k-4). Write an expression in simplest form to represent the perimeter of the square

20k-16

Step-by-step explanation:

There are four sides in a square, and all the sides are the same length. Because one side is 5k-4, we just have to do 4(5k-4) to get 20k-16

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

3 is greater then both of those numbers
