The equivalent expression is $-6 \rm x-9$ .

<h2>We have to determine</h2>

Which expression is equivalent to $\rm -9 \left ( \dfrac{2}{3}x +1 \right )$ ?

<h3>According to the question</h3>

Expression; $\rm -9 \left ( \dfrac{2}{3}x +1 \right )$

To solve the given expression follow all the steps given below.

By applying the distributive property of multiplication;

$\rm a(b+c) = ab+ ac$

Then,

The equivalent expression is,

$\rm = -9 \left ( \dfrac{2}{3}x +1 \right ) \\
\\
= (-9) \times \dfrac{2}{3}x+(-9)(1)\\
\\
= (-3) 2x + (-9)\\
\\
= -6x-9$

Hence, the equivalent expression is $-6 \rm x-9$ .
