question
which expression is not equivalent to 24 + 12?
answer
\\( 3(8 + 4) \\)
\\( 6(4 + 2) \\)
\\( 3(8 + 9) \\)
\\( 2(12 + 6) \\)

Explanation:

Step1: Calculate \(24 + 12\)

First, we find the value of the original expression \(24 + 12\).
\(24+12 = 36\)

Step2: Evaluate \(3(8 + 4)\)

Using the distributive property \(a(b + c)=ab+ac\), we have:
\(3(8 + 4)=3\times8+3\times4 = 24 + 12=36\)

Step3: Evaluate \(3(8 + 9)\)

Using the distributive property:
\(3(8 + 9)=3\times8+3\times9=24 + 27 = 51\)

Step4: Evaluate \(6(4 + 2)\)

Using the distributive property:
\(6(4 + 2)=6\times4+6\times2 = 24+12 = 36\)

Step5: Evaluate \(2(12 + 6)\)

Using the distributive property:
\(2(12 + 6)=2\times12+2\times6=24 + 12 = 36\)

Answer:

\(3(8 + 9)\)
