What is the minimum perimeter of a rectangle that has an area of 625 square feet?

100 feet.

Step-by-step explanation:

The minimum perimeter of a rectangle with fixed area is always a square.

Length of square = √625 = 25.

Perimeter of square = 4 * 25 = 100 feet.

1 and 2

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
