Answer:
6 for a btu not sure
Step-by-step explanation:
My recommendation would be to factor..
x² + 4x + 3 = 0 factor the left side into two binomials
(x + 3)(x + 1) = 0 set each of these binomials equal to zero and solve
x + 3 = 0 Implies x = -3
x + 1 = 0 implies x = -1
So 3 2/3 is about 3.67 so it would go in between 3.65 and 3.7. So it would be the second answer.
Make it a trinomial by using the FOIL method.
