Answer:
I believe this is right. Answer: 6/7
Step-by-step explanation:
5+1 = 6
The denominator stays the same.
Answer:
9pr = 2q^2
Step-by-step explanation:
28.
px^2 + qx + r = 0
If one root is A then the other root is 2A
We have A + 2A = -q/p and A*2A = r/p
So 3A = -q/p so A = -q/3p and A^2 = r/2p so A = √ (r / 2p)
Equating these 2 equations:-
-q/3p = √(r / 2p)
q^2 / 9p^2 = r / 2p
9p^2r = 2pq^2
9pr = 2q^2 (answer)
The answer to the equation is 15
Answer:
Im pretty sure it's A because Z and AZ are collinear
