Answer:
true
Step-by-step explanation:
There is no distribution (unless you count substitution) in the second set of terms.
Edit: I think I get what your question is now. You are supposed to distribute to every term inside the parenthesis (false)
Start with
Add 2x to both sides:
Subtract 21 from both sides:
Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:
So, the answer is 
8x -5+2 x
8x+2x-5 ( combine like terms)
answer:
10x-5 or -5+10x
First, look at the x axis (this is the one labeled Minutes Used per month)
Find the number 40, then look at where the lines meet on that line. The red line for Plan B it’s at 8 dollars. The blue line for Plan A is at 4 dollars.
Plan B costs more.
To find the difference, subtract 4 from 8.
$8 - $4 = $4
Plan B costs 4 dollars more than Plan A.
