Usually when asking for common factors they ask you to compare two or more different numbers but the factors of 32 are:
1, 2, 4, 8, 16, 32
We have to use Pythagorean theorem that says :

The missing length of the triangle is : 36 feet
So what are we trying to find the reduced fraction or inverse operation
The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units
Answer:
Number A is correct I think, coz if uu take the feet convert them into decimals u'll get accurate answers
