Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.

15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.

How many terms are in a^2-ab+8b+b^2-1

DanielleElmas [232]

Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:
$a^2-ab+8b+b^2-1$
- First term: $a^2$
- Second term: $-ab$
- Third term: $8b$
- Fourth term: $b^2$
- Fifth term: $-1$

We can conclude that there are 5 terms in the polynomial $a^2-ab+8b+b^2-1$ .
