Answer:
(6x + 1)(x + 9)
Step-by-step explanation:
6x^2 +9 = - 55x
6x^2 + 55x + 9 = 0
55 is a pretty big number compared to either 6 or 9. Not only that, but 6*9 = 54.
So the answer is going to depend on multiply 6x together with 9
(6x + __ ) ( x + 9)
Now what goes were the underline is?
You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.
(6x + 1 )(x + 9) Answer
2.2 = 1.4d + 3.7 - 5.4d = 3.7 - 4d
4d = 3.7 - 2.2 = 1.5
d = 1.5/4 = 0.375
