A) The terms \(6x\) and \(12x\) have same variable \(x\) with exponents equal to 1 and are therefore like terms. The terms \(5\) and \(-6\) are numbers and therefore like terms. B) The terms \(2x^2\) and \(9x^2\) have same variable \(x\) with exponents equal to 2, they are like terms. The terms \(-4\) and \(+9\) are numbers and therefore like terms. C) The terms \(\frac{x}{5}\) and \(\frac{x ...
