Answer:
It is B. Commutative Property of Addition. I selected d from the other answer and it was wrong, just trust me it b. Commutative.
Hope this helps you.
Answer:supplementary
Step-by-step explanation:By the angles shown
Answer:
-5
Explanation:
First, expand.
r + b - 9 × b + g.
If r = 9, b = 5, and g = -6, this would be the answer:
9(r) + 5(b) - 9 = 5
×
5(b) + -6(g) = -1
5 × -1 = -5
Answer:

Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>

Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=> 
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
