Use the process of elimination.
There is a positive b value and a negative c value, which means that there is a negative factor and positive factor. This eliminates A and C.
Multiply out the factors in B and D:
B
(6d - 1)(2d + 1)
6d * 2d = 12d^2
6d * 1 = 6d
2d * -1 = -2d
12d^2 + 4d - 1
D
(6d + 1)(2d - 1)
6d * 2d = 12d^2
6d * -1 = -6d
2d * 1 = 2d
12d^2 - 4d - 1
The answer is B.

Step-by-step explanation:
As you know, the domain is the values "x" can safely take on.
well, for a logarithmic expression, it can never have an expression of 0, namely in this case, x + 4 must never be 0, since such a logarithm doesn't exist.
now, x + 4 = 0 ---> x = -4.
thus if "x" ever becomes -4, we'd end up with log₃(-4+4), or log₃(0), which is a no dice.
so the domain is all values except -4.
48.30 you move the decimal point back (to the left) to get 10 percent then since 5 is half of 10 to get the rest of the 15 percent you take half of ten percent witch is 5 and add the 10 and 5 percent to get the total 15 percent witch is 6.30 then add 6.30 for a total of what he paid
