Which expression represents adding (5) to twice the difference of (x) and (2)?

Answer and explanation

Correct answer: \(2(x-2)+5\)

The difference of \(x\) and \(2\) is \(x-2\). Twice this entire difference is \(2(x-2)\), and adding 5 gives \(2(x-2)+5\). In option A, only \(x\) is doubled rather than the whole difference \(x-2\). Exam tip: Use brackets when a multiplier applies to an entire difference.
