We’re left with 3x + 10
Answer:
B
Step-by-step explanation:
Given
+ + = 0 , then
= 0 , so
yz + zx + xy = 0
Now
(x + y + z)² = x² + y² + z² + 2(xy + yz + zx) , that is
1² = x² + y² + z² + 2(0) , thus
x² + y² + z² = 1
Answer: I believe the answer to that question is no
Step-by-step explanation: So you see, when there are not symbols that represent addition or subtraction, or any other operation, it's not considered a question.
