Answer:

Step-by-step explanation:

3ab + 7a² + 2b² - (7a² - 4ab + 2b²) = 3ab + 7a² + 2b²  - 7a² + 4ab - 2b²

Now combine like term. Like terms have same variable with same power.

= <u>3ab + 4ab</u>  <u>+ 7a² - 7a²</u>  + <u>2b² - 2b²</u>

= 7ab

Notebooks cost $1.20 each. This weekend they will be $.80 What percentage is the sale?
geniusboy [140]
The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4    Now divide .4 by 1.2 to get your answer.

\frac{.4}{1.2}=.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so \frac{2}{3} of 12 would equal 8.

Does you understand it now?
