Answer: 10n^2 - 10
Step-by-step explanation:
(5n - 5)(2+2n) becomes (5n-5)(2n+2)
= (5n)(2n) + (5n)(2) + (-5)(2n) + (-5)(2)
= 10n^2 - 10

Answer: 7/20</h3>
=========================================================
Work Shown:
2/5 = 8/20 .... multiply top and bottom by 4
1/4 = 5/20 ..... multiply top and bottom by 5
The fractions 2/5 and 1/4 are equivalent to 8/20 and 5/20 in that order.
These new equivalent fractions add to 8/20+5/20 = (8+5)/20 = 13/20
After two days, Pete has read 13/20 of the book.
This leaves 1 - (13/20) = 20/20 - 13/20 = (20-13)/20 = 7/20 of the book left to be read.
Note how 13/20 + 7/20 = (13+7)/20 = 20/20 = 1
