Answer:
the distributive property of 18+42 is multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Step-by-step explanation:
Firstly you forgot to attach the mathematical work along with your question. I am answering the question based on my research and knowledge and hope that it helps you. "The simplification performed in step 2 is invalid or incorrect" is the statement that <span>best applies to the sample mathematical work. The correct option among all the options given in the question is option "B".</span>
The first thing we are going to do is distribute:
=<span>4x+(6)(3x)+(6)(−2)
</span>=<span><span><span><span>4x</span>+<span>18x</span></span>+</span>−<span>12
</span></span>Second thing we are going to do is C<span>ombine Like Terms:
</span>=<span><span>4x+18x</span>+<span>−<span>12
=</span></span></span><span>(<span><span>4x</span>+<span>18x</span></span>)</span>+<span>(<span>−12</span><span>)
</span></span>And your final answer is:
<span>22x</span>+<span>−<span>12</span></span>
I hope this helps you! :)
