Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
We can use #11 as an ex.
7ab and 4 ab
So we combine 7 and 4 (multiply)
=28
Then combine "a". On both sides they are 2 a"s so it would be a^2 and same for b . b^2
Answer: 28a^2b^2.
hope it helps*

x^2 - 14x - 32 = x^2 - 16x + 2x - 32 = x(x-16) + 2(x-16) = (x - 16)(x + 2)

⇒ x^2 - 14x - 32 = (x - 16)(x + 2)</h2>

2n^2 - 7n - 15 =

The slope of that line is -3/4, or -0.75.
