This is for my school city, and a test worth half my grade pt.5 (Final part)

Question

This figure is used as part of a visual description of an algebraic statement.

1. 
   
2. Which of the following can be that algebraic statement?
3. A. a⋅b=c
4. B. a^2+b^2=c^2
5. C. a^2⋅b^2=c^2
6. D. 12(a+b)=c
7. 
   
8. 
   
9. 
   

Answer 1

B is correct. a^2 + b^2 = c^2

in the diagram that's the same as 3^2 + 4^2 = 5^2

9+ 16 = 25

that diagram has been used as a proof of the pythagorean theorem. Count the squares on the right and below. they sum to the squares on the left side
