In this expression, marianne claims that 2x and –x are not like terms because –x does not have a coefficient. is she correct? explain your reasoning.

No, Marianne is not correct. The coefficient of -x is -1. The "1' is just omitted and only the negative is kept because showing 1 is unnecessary as 1 multiplied by anything is itself.

answer: 40.95

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
