Question

Which expression is equivalent to 8 x x - 7 - 3 x - 7 2 x - 14 , where x &#62; 7 ?

Accepted Answer

Choice B is correct. The given expression has a common factor of 2 in the denominator, so the expression can be rewritten as 8 x x - 7 - 3 x - 7 2 x - 7 . The three terms in this expression have a common factor of x - 7 . Since it's given that x > 7 , x can't be equal to 7 , which means x - 7 can't be equal to 0 . Therefore, each term in the expression, 8 x x - 7 - 3 x - 7 2 x - 7 , can be divided by x - 7 , which gives 8 x - 3 2 . Choice A is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
