............

**Answer:**

1/y^3

**Step-by-step explanation:**

A. (8x + 7)(2x-7)

O B. (4x + 7)(4x - 7)

O C. (8x-7)(2x-7)

O D. (4x-7)(4x-7)

**Answer:**

B

**Step-by-step explanation:**

16 x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b), thus

16x² - 49

= (4x)² - 7²

= (4x + 7)(4x - 7) → B

**Answer:**

B

**Step-by-step explanation:**

**There is no number between 16x and 49. So only think about the number being squared for 49; which is 7. **

**Then 49 is negative, so you must have both positive and negative signs in both parenthesis. Otherwise, positive times positive is positive, and negative times negative is also positive. **

4x4 is 16. That's why you put fours in front of Xs.
