D , because they are both completely unrelated which means one does not depend on the other. bringing an umbrella is independent from going to school knowing u have a test.
Answer:
i believe the answer is D
Step-by-step explanation:
im not entirely sure but that's what i got.
-13 +3x +8 = 3x + (-5)
-9x + 15 - x -10 = -10 x + 5
The other two don't match
6x = n²-16
n²-6x-16=0 -16=-8*2, -6=-8+2
(n-8)(n+2)=0
n-8=0, n+2=0
n=8, n=-2
Negative solution is -2.
