To find the cost of each book, you need to divide the money spent on all of the books by the number of books.
$39 / 10 = $3.90 per book
Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
3,807,000 + 4,339,000= <span>8,146,000
or if you wanted it like this:
3,807,412 + 4,339,789 = </span><span>8,147,201 (8,147,201 Rounded)</span>
The fraction for 54 is 270/5
