Answer:
B
Explanation:
-42 is a integer, but not irrational, and whole numbers are all positive except for 0.
A^2 + b^2 = c^2....this is the pythagoream theroum (sorry, probably spelled it wrong)....it is used for right triangles.
a and b are ur legs of the triangle and c is the hypotenuse. Therefore, the value of a^2 is the value of one of the legs, squared.
OR. if u mean this..
a^2 + b^2 = c^2
a^2 = c^2 - b^2
Answer:
Both are correct
-1 x -1 = 1
-1 x -1 x -1 = -1
