Let's solve this problem graphically. Here we have the following equation:

So we can rewrite this as:

So the solution to the equation is the x-value at which the functions f and g intersect. In other words:

Using graphing calculator, we get that this value occurs at:

Answer:
The length of side of largest square is 15 inches
Step-by-step explanation:
The given suares are when joined in the way as shown in picture their sides form a right agnled triangle.
Area of square 1 and perimeter of square 2 will be used to calculate the sides of the triangle.
So,
<u>Area of square 1: 81 square inches</u>

<u>Perimeter of square 2: 48 inches</u>

We can see that a right angled triangle is formed.
Here
Base = 12 inches
Perpendicular = 9 inches
And the side of largest square will be hypotenuse.
Pythagoras theorem can be used to find the length.

Hence,
The length of side of largest square is 15 inches
9 = 2(6) - b
9 = 12 - b
-3 = b
