Hi!
The table above is showing how to plug in a variable to x. For an example,
when x= 4 would equal 17. How we would get this is substitute x with 4 and use our order of operations.
To get 68, we would do this in reverse. We would add 3 to both sides to eliminate the -3 to have a remainder of
Divide both sides by five to solve for x.
We can also check our math and plug in 17/5 into x

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
