Answer:
<h2>10</h2>
Step-by-step explanation:
<h3>-2n - 6 = ?</h3><h3 /><h3>let n be -8</h3><h3 /><h3>-2 (-8) - 6 = ?</h3><h3 /><h3>= 10</h3>
Simple...
you have: 3(a+4)=3a+4
You're deciding whether it's true or false..to do so, simplify it..
3(a+4)=3a+4
3*a=3a
3*4=12
3a+12=3a+4
As we can see here, they do no match. False.
Thus, your answer.
