Answer:
Step-by-step explanation:
and it's an arithmetic sequence.
------------------------------
First, you would add 9x to both sides so that you get:
x^2 + 9x + 20 = 0.
Then, you want to factor. You want coefficients of x that add to 9 and have the constants add to 20:
(x + 5) * (x + 4) = 0
The answer is (C).
The answer is 105, did the assignment got it right
Answer:
-6
Step-by-step explanation:
