Step-by-step explanation:
To subtract 2 1/2 - 1 3/5, first, you need a common denominator for the fractions, which is 10.
The subtraction becomes
2 5/10 - 1 6/10
Now you need to subtract 1 6/10 from 2 5/10.
Since the fraction part involves the subtraction 5/10 - 6/10, we need to borrow. You must change 2 5/10 to a mixed numeral with a larger numerator than 5, so you can subtract 6/210 from it.
Start with 2 5/10.
Borrow 1 from the 2. The 1 you borrow from 2 will be added to 5/10.
You think of the borrowed 1 as 10/10. Now you add 10/10 to 5/10.
2 5/10 becomes 1 15/10. Now that the fraction has a numerator grater than 6, you can do the subtraction.
2 5/10 - 1 6/10 =
= 1 15/10 - 1 6/10

Answer:
A
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor.
(2x + 5)(4x + 4)
= 2x(4x + 4) + 5(4x + 4) ← distribute both parenthesis
= 8x² + 8x + 20x + 20 ← collect like terms
= 8x² + 28x + 20 → A
