Answer:

(7x + 5)(7x - 5)

Step-by-step explanation:

49x² - 25 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

49x² = (7x)² ⇒ a = 7x

25 = 5² ⇒ b = 5

49x² - 25

= (7x)² - 5² = (7x + 5)(7x - 5)

What is the value of x in the diagram?

Ksenya-84 [330]

The red arrows mean the lines are parallel. Since all angles are equal, the larger triangle is similar to the smaller one. Then corresponding sides have the same ratio
(4x -2)/9 = (3x+2)/12
x(4/9 -3/12) = (2/12) +(2/9)
x = (7/18)/(7/36) = 2 . . . . . . . . . corresponding to the 3rd selection
