Answer:

BC = 13

Step-by-step explanation:

AB + BC = AC, substitute values

4x + 2x - 3 = 45, that is

6x - 3 = 45 ( add 3 to both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Hence

BC = 2x - 3 = (2 × 8) - 3 = 16 - 3 = 13

Answer: x = 8

(the correct answer was not provided as an option)

<u>Step-by-step explanation:</u>

$log_2(x-6)+log_2(x-4)=log_2(x)\\\\log_2[(x-6)(x-4)]=log_2(x)\\\\(x-6)(x-4)=x\\\\x^2-10x+24=x\\\\x^2-11x+24=0\\\\(x-3)(x-8)=0\\\\x=3\qquad x=8\\\\\\\text{The term after the log symbol (inside the parenthesis) must be greater than 0!}\\\\Check:\\3-6>0\ \text{FALSE --- so 3 is not a valid solution}\\\\8-6>0\ \text{TRUE}\\8-4>0\ \text{TRUE}\\8>0\ \text{TRUE --- 8 is a valid solution because it is true for all}$
