Answer 1

To determine which expressions are equivalent using the Associative Property, we can look at the expressions you have provided:

1. \(-3 \cdot (4x \cdot -2) \cdot -6y\)
2. \(18 - 8x\)
3. \((-3 \cdot 4x) \cdot (-2 \cdot -6y)\)
4. \((-3 \cdot 4x) \cdot -2 \cdot -6y\)

The Associative Property states that when multiplying, the way we group the factors does not change the product.

Step 1: Simplifying the first expression:

\(-3 \cdot (4x \cdot -2) \cdot -6y\)

Calculate \(4x \cdot -2 = -8x\). Then substitute:

\[ -3 \cdot (-8x) \cdot (-6y) = -3 \cdot 8xy \cdot -6 = 144xy \]

Step 2: Check against the other expressions.

• For Expression 2: \(18 - 8x\), we see that this expression is not equal to \(144xy\).

• For Expression 3: \((-3 \cdot 4x) \cdot (-2 \cdot -6y)\)

First, calculate \(-2 \cdot -6y = 12y\):

\[ (-3 \cdot 4x) \cdot 12y = (-12x) \cdot 12y = -144xy \]

This also isn't equal to \(144xy\).

• For Expression 4: Starting with the same calculation:

\((-3 \cdot 4x) \cdot -2 \cdot -6y = -12x \cdot -6y = 72xy\)

This is also not equal to \(144xy\).

Step 3: Determine equivalences.

Among these expressions, we can see that:

• Expressions 1 calculates to \(144xy\).
• Expression 3 calculates to \(-144xy\).
• Expression 4 calculates to \(72xy\).
• Expression 2 is not equivalent either.

Since none of the expressions calculated to the same value, none of the provided expressions are equivalent.

The correct related expression here relies solely on the understanding of how multiplication groups via the Associative Property, but these specific results don't yield equivalency amongst the provided expressions.

In conclusion, based on our analysis and simplification, none of the original expressions are equivalent due to differing results.

Answer 3

I apologize for the confusion! Let's simplify and compare the expressions clearly.

Given the first expression:

1. \(-3 \cdot (4x \cdot -2) \cdot -6y\)

We'll simplify it step by step:

1. \(4x \cdot -2 = -8x\)
2. So, \(-3 \cdot (-8x) \cdot -6y = 24xy \cdot -6 = -144xy\)

Now let's evaluate the expressions:

Comparing the Expressions:

• Expression 1: \(-3 \cdot (4x \cdot -2) \cdot -6y = -144xy\)

• Expression 2: \(−7xy\) (not equal to \(-144xy\))

• Expression 3: \((-3 \cdot 4x) \cdot (-2 \cdot -6y)\)

  • Simplifying: \((-3 \cdot 4x) = -12x\) and \((-2 \cdot -6y) = 12y\)
  • So, \(-12x \cdot 12y = -144xy\) (this matches Expression 1)

• Expression 4: \((-3 \cdot 4x) \cdot -2 \cdot -6y\)

  • Again, \(-3 \cdot 4x = -12x\)
  • Then we multiply: \(-12x \cdot -2 = 24x\) and then \(24x \cdot -6y = -144xy\) (this also matches Expression 1).

Conclusion:

Thus, the equivalent expressions are:

• Expression 1: \(-3 \cdot (4x \cdot -2) \cdot -6y\)
• Expression 3: \((-3 \cdot 4x) \cdot (-2 \cdot -6y)\)
• Expression 4: \((-3 \cdot 4x) \cdot -2 \cdot -6y\)

Therefore, you can pick Expression 3 or Expression 4 as equivalent to Expression 1.

If you must pick one, I recommend Expression 3 because it clearly shows the associative grouping.
