Answer:

$\large\boxed{12\sqrt2}$

Step-by-step explanation:

a - side of square

The formula of a perimeter of a square:

$P=4a$

We have P = 48. Substitute:

$48=4a$ divide both sides by 4

$12=a\to a=12$

You can use the Pythagorean theorem, and calculate the length of a diagonal or use the formula of a diagonal of a square:

$d=a\sqrt2$

Substitute:

$d=12\sqrt2$

A science class is tracking the progress of plant growth. The class starts the experiment with a plant five centimeters high. Th

Goryan [66]

The second sentence above helps with this answer. The y-intercept is the initial height of the plant before any documentation of time and growth was collected. Since the plant was initially 5 cm high, we can use it as a starting point for the data. For example, using x=0 indicates 0 day and if we substitute it in you will see that we are left with a solution of 5. This will let those reading the data to understand that the plant was already at 5 cm when the experiment began.
