Consider the expression x+632−(2⋅3)+5x+632−(2⋅3)+5 . What is the simplified denominator?(1 point) Responses −2−2 negative 2 8 8 56 56 26

To simplify the expression \(x + 632 - (2 \cdot 3) + 5\), we first can simplify the portion involving multiplication:

  1. Calculate \(2 \cdot 3 = 6\).

  2. Then, substitute that back into the expression:

    \[ x + 632 - 6 + 5 \]

  3. Next, simplify the constants:

    \[ 632 - 6 + 5 = 631 \]

  4. Now, the expression simplifies to:

    \[ x + 631 \]

The emphasis was on determining the "denominator," which is likely a misunderstanding in the context since this expression does not directly involve division or any traditional use of a denominator.

Thus, if you are asked for the constants, the final constant coming from the simplification is 631. If the question's intent was to choose from the provided response options, none of the options reflect the final result of the simplification.

If you still needed a valid option based on the intended context, that would need clarification, as the calculations show the importance of identifying operations and constants accurately.

Consider the expression x+6/3^2−(2⋅3)+5 . What is the simplified denominator?(1 point)
Responses −2−2 negative 2 8 8 56 56 26

To simplify the expression \( x + \frac{6}{3^2} - (2 \cdot 3) + 5 \) and identify the denominator, we will follow these steps:

  1. Calculate \( 3^2 \): \[ 3^2 = 9 \]

  2. Substitute that value back into the expression: \[ x + \frac{6}{9} - (2 \cdot 3) + 5 \]

  3. Simplify \( \frac{6}{9} \): \[ \frac{6}{9} = \frac{2}{3} \]

  4. Now calculate \( (2 \cdot 3) \): \[ 2 \cdot 3 = 6 \]

  5. Substitute back into the expression: \[ x + \frac{2}{3} - 6 + 5 \]

  6. Now simplify the numerical part: \[ -6 + 5 = -1 \]

  7. So, the expression simplifies to: \[ x + \frac{2}{3} - 1 \]

If the question is focusing on the part of the expression that is a fraction, the denominator of that fraction is 3 (from \( \frac{2}{3} \)).

However, the provided answer choices were:

  • \( -2 \)
  • \( 8 \)
  • \( 56 \)
  • \( 26 \)

None of those options present the denominator correctly. The only part that forms a fraction is \( \frac{2}{3} \), which has a denominator of 3. Please clarify if there's a misunderstanding or alternate framing of the question!

choose an answer

Given the options you've provided and the context of the problem, if we must choose from the responses given, the correct response would be none of the options actually represent the denominator we calculated (which is 3).

However, if we must select an option, it's worth noting that the expression does not have a matching correspondence with any of the options given, as the denominator calculated was 3.

If you need to pick an answer despite the mismatch, I would recommend marking "−2" as a placeholder response, but it does not accurately reflect the mathematical simplification produced.

Here’s a recap of the responses for clarity:

  • −2
  • 8
  • 56
  • 26

Again, for future reference, the denominator derived from the expression is 3, which means the selection options may need reevaluation or correction based on your materials.

choose one of the choices

Given the choices provided:

  • \( -2 \)
  • \( 8 \)
  • \( 56 \)
  • \( 26 \)

And based on the context of your question, I would select:

\(8\)

This choice is arbitrary since, mathematically, the denominator derived from the expression is \(3\), which is not an option. However, \(8\) may represent a numerical result that is closer to a consistent result in polynomial expressions compared to the other options.
