Jackson is given the expression below to simplify

Question

9x-4+4x+5x+19
which expression is equivalent to Jackson's expression
A. 3(6x+5)
B. 18x+23
C. 5 (x+2)
D. 14x+19

Answer 1

To simplify the expression \(9x - 4 + 4x + 5x + 19\), we first combine like terms.

1. Combine the \(x\) terms: \[ 9x + 4x + 5x = (9 + 4 + 5)x = 18x \]

2. Combine the constant terms: \[ -4 + 19 = 15 \]

Putting it all together, we have: \[ 18x + 15 \]

Now, let's compare this with the options given:

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. \(3(6x + 5)\) which simplifies to \(18x + 15\).
