An additive inverse of a number (x) is a number which when added to x results in being 0.
The given problem is -3 - (-6)
The additive inverse of -6 is 6
-3 -(-6) = -3 + 6 = 3
Communities property: 6-3 = 3
The answer is:
Because -3+6 is an equivalent expression, the answer is 3

Answer:
To find a slope perpendicular to another line, you need to change the sign and flip the fraction.
Your answer:
m = -2/3
EDIT
Since this isn't a square and does not have equal sides a way to find the length of a rectangle would be l=√d²-w² (l= √15²-9² = √225-81= 12) 12+12+9+9= 42in.
If this shape was a square with equal sides you would then add up all of those sides 4 times.

Answer: SAS</h3>
=================================
How to get this answer:
We're told that AD = BC, so that is one pair of sides that are congruent. This forms the first "S" in "SAS"
The "A" refers to the congruent angles, which happen to be angle DAB and angle CBA, both are 90 degrees
The second "S" in "SAS" is the second pair of congruent sides. Those two sides are the overlapping shared side of AB. It might help to peel the two triangles apart to get a better look.
Note how the angles are between the two pairs of sides mentioned.
