To find the expression equivalent to \(3x + 2\), let's simplify each option:
A. \(x + x + x + 1 + 1\)
This simplifies to \(3x + 2\). ✅
B. \(x + x + 1 + 1 + 1\)
This simplifies to \(2x + 3\). ❌
C. \(3x + 6\)
This simplifies to \(3x + 6\). ❌
D. \(3 + x + 2\)
This simplifies to \(x + 5\). ❌
The only expression that is equivalent to \(3x + 2\) is option A: \(x + x + x + 1 + 1\).
Let's simplify the expression given to Jackson step by step:
\[ 9x - 4 + 4x + 5x + 19 \]
Combine the \(x\) terms:
Combine the constant terms:
So the simplified expression is: \[ 18x + 15 \]
Now, let's compare this to the options provided:
A. \(3(6x + 5) = 18x + 15\) ✅
B. \(18x + 23\) ❌
C. \(5(x + 2) = 5x + 10\) ❌
D. \(14x + 19\) ❌
The equivalent expression to Jackson's expression is A. \(3(6x + 5)\).
