Answer:
Quotient = a²+ 4a- 2
Step-by-step explanation:
(8a3+31a2-20a-5)/(8a-1)
=
<u> a² +4a-2 ⇒ quotient</u>
(8a-1)√(8a3+31a2-20a-5)
8a²- a² ⇒ Multiplying (8a-1) by a²
<u> - + </u> ⇒ Changing signs
32a²- 20a- 5
32a²- 4a ⇒ Multiplying (8a-1) by 4a
<u> - + </u> ⇒Changing signs
-16a -5
- 16a +2 ⇒ Multiplying (8a-1) by -2
<u> + - ⇒</u> Changing signs
-7 ⇒ Remainder
We follow the steps of simple division to get the quotient which is a²+ 4a- 2
We multiply (8a-1) by factors such as a², +4a and -2 to get the same terms as given in the dividend.

Answer: Mary's backpack was a better buy.
Step-by-step explanation:
First, you figure out the cost of Mary's backpack. To do this, you find the amount taken off the original price by doing 65 x 25%.
65 x 25% = 16.25. This is the price deducted form the original. Therefore the new price is $48.75 because $65(original)- $16.25(amount taken off original)= $48.75.
Now onto Roberto. First, you find the price taken off by doing 75 x 30%. This gets you $22. 50.
75 x 30%= 22.5
Next, you deduct the original from the amount taken off.
75-22.5= $52.50
Since 48.75 is less than 52.50, Mary's backpack was a better buy.
