Select the TWO expressions that are equivalent to the given expression. (2x+2)−(3x+11) (1 point) Responses −x+13 negative x plus 13 5x+9 5 x plus 9 5x+13 5 x plus 13 −x−9 negative x minus 9 2x−3x+2−11 2 x minus 3 x plus 2 minus 11 −x+9 negative x plus 9 2x−3x+2+11

1 answer

To simplify the expression \((2x + 2) - (3x + 11)\), we follow these steps:

  1. Distribute the negative sign across the second parentheses:

    \[ 2x + 2 - 3x - 11 \]

  2. Combine like terms:

    • Combine \(2x\) and \(-3x\): \[ 2x - 3x = -x \]

    • Combine \(2\) and \(-11\): \[ 2 - 11 = -9 \]

Thus, the simplified expression is:

\[ -x - 9 \]

Now, let's identify which of the responses given are equivalent to \(-x - 9\):

  1. \(-x + 13\) - NOT equivalent
  2. \(5x + 9\) - NOT equivalent
  3. \(5x + 13\) - NOT equivalent
  4. \(-x - 9\) - EQUIVALENT
  5. \(2x - 3x + 2 - 11\) - This simplifies to \(-x - 9\) as shown above, so it is EQUIVALENT.
  6. \(-x + 9\) - NOT equivalent
  7. \(2x - 3x + 2 + 11\) - This simplifies to \(-x + 13\), which is NOT equivalent.

Therefore, the two equivalent expressions are:

  1. \(-x - 9\)
  2. \(2x - 3x + 2 - 11\) (which simplifies to \(-x - 9\)).

So the answers are:

  1. \(-x - 9\)
  2. \(2x - 3x + 2 - 11\)
