Answer:
x ≈ 4.2
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(72°) = b/x = 13/x
x = 13/tan(72°) ≈ 4.223956
Rounded to the nearest tenth, x ≈ 4.2.
6x^2 +30x - 36
6( x^2 +5x -6)
6(x^2 -x+6x-6)
6[ x(x-1) 6(x-1)]
(x-1) (x+6)
Looking at the table, we can readily say that the correct
answer to this question is:

The
amount dissolved always increases with time unless it has already reached the
