we are supposed to explain
Which situation could be solved using the equation 
As we can see in the given equation , one number is -4 and the other number is 4
When we add two number of same value but opposite in sign we get zero.
This equivalent to the real life situation of paying a post paid bills.
Suppose you are using a post paid service , and the bills gets generated at the end of the month.
Suppose the bills amount is $x.
Once you pay that bills , then total outstanding again becomes $0.
Because 
Area of a rectangle is length * width.
7ab * 2a is the same as 7(2) * a(a) * b
7 * 2 = 14
a * a = a²
b = b
Put it all together.
14a²b is your monomial.
If he bought the bike for $400 and lost 35% of his profit, you would divide 35 by 100. Next, you would multiply that number (0.35) by 400. When you do that, you get an answer of $140. In conclusion, if he bought the bike for $400 and sold it at a loss of 35%, he would lose $140 from that $400.
Additionally, if you wanted to know what exactly he sold it for, you would simply subtract 140 from 400. Which would be $260.
So, he bought the bike for $400, but when he resold it, he lost $140 of that pay. Basically, he resold the bike for $260.
