B). (x + 7)(4x – 7)
C). (2x + 7)(2x – 7)
D). (2x + 7)2

(2x + 7)(2x - 7)

Step-by-step explanation:

Given:

4x² - 49

Find:

Factories

Computation:

4x² - 49

Using Identity

⇒ a² - b² = (a + b)(a - b)

⇒ 4x² - 49

⇒ (2x)² - (7)²

(2x + 7)(2x - 7)

the anwser is d) 75°

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
