If the area of square 1 is 250 units squared, and the area of square 3 is 120 units squared, what is the area if square 2? explain your reasoning.

The area of square 2 is 130 units square

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a square is

where

b is the length side of the square

Let

b1 ----> the length side of square 1

b2 ----> the length side of square 2

b3 ----> the length side of square 3

Applying the Pythagoras Theorem

-----> equation A

we have

Remember that

so

substitute in the equation A and solve for b2^2

therefore

The area of square 2 is 130 units square

no

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
