100b + 70 because it can't be simplified further than that
Answer:
I don't remember the name of the law, but it states that when resistors are connected in series they put up one singular resistance. so,
Let smaller resistance be x
greater resistance is 3x
According to the question,
x+3x=12
4x=12
x=3
therefore,
resistors are of 3 ohms and 3×3=9 ohms
-8 + k = -17
k = -17 + 8
k = 8 -17
k = -9
Normally you will see these expressions in reverse order with descending powers of the variable.
-4y^4 + y^3 - y^2 + 11y + 9
So you start with the high order terms and end with a constant.
Each of the 223 million people put $10 back into circulation every year.

So every year, this much money goes into circulation, and this is how much that goes into circulation the first year.

This is how much that will be in circulation after 2 years.

This is how much that will be in circulation after 3 years.
So we can create the table:
