question
which expression is not equivalent to $60 + 12$
answer
$\circ$ $6(54 + 2)$ $\circ$ $3(20 + 4)$
$\circ$ $2(30 + 6)$ $\circ$ $6(10 + 2)$

Explanation:

First, calculate the value of \(60 + 12\), which is \(72\). Then, we will calculate the value of each option:

Step 1: Calculate \(60 + 12\)

\(60+12 = 72\)

Step 2: Analyze Option 1: \(6(54 + 2)\)

First, calculate the expression inside the parentheses: \(54 + 2=56\). Then multiply by 6: \(6\times56 = 336\). Since \(336
eq72\), this expression is not equivalent to \(60 + 12\). But let's check the other options to be sure.

Step 3: Analyze Option 2: \(3(20 + 4)\)

Calculate inside the parentheses: \(20+4 = 24\). Then multiply by 3: \(3\times24 = 72\). This is equivalent to \(60 + 12\).

Step 4: Analyze Option 3: \(2(30 + 6)\)

Calculate inside the parentheses: \(30+6 = 36\). Then multiply by 2: \(2\times36 = 72\). This is equivalent to \(60 + 12\).

Step 5: Analyze Option 4: \(6(10 + 2)\)

Calculate inside the parentheses: \(10+2 = 12\). Then multiply by 6: \(6\times12 = 72\). This is equivalent to \(60 + 12\).

Answer:

\(6(54 + 2)\) (the first option)
