Which option gives the correct sum of (3x+2) and (x-5)?

Answer and explanation

Correct answer: \(4x-3\)

In \((3x+2)+(x-5)\), combine like terms: \(3x+x=4x\) and \(2-5=-3\). Therefore, the sum is \(4x-3\). The option \(4x+7\) results from adding the constants with an incorrect sign. Exam tip: while adding polynomials, combine only terms with the same variable and exponent.
